The received information on radar processor that collected from radar transmitter sometimes are not good enough to be displayed on the radar display. This problem makes user difficult to distinguish noise and object. One technique that can be used to solve this problem is by grouping the objects based its density. One of clustering method used to handle object clustering automatically is DBSCAN algorithm. Unfortunately, this algorithm has a high complexity that will interfere the radar performance. To overcome both of the problems, need a quick method that able to classify the object and the noise. This paper proposed a new clustering algorithm by combining ADBSCAN algorithm using Marked Boundary Object (MBO) as the policy connectivity. The developed algorithm has successfully implemented on PPET-LIPI radar display. This algorithm is shown promising running time performance than the original DBSCAN algorithm (increase of approximation 71%).

Portable through wall radar display and control system is bridge between the radar signal process system and users. On the one hand, radar display and control system receives the origin image signal and present it to users after processed it, on the other hand, the system receives the users' instructions and passes it to the signal process system.

Objective: The aim of this study is developing the navigation radar display of navy ship with ecological interface design (EID) framework. Background: Navy ship radar operator must perform navigation support tasks by monitoring the complex and diverse information presented on the radar display. Current radar display is limited in effective navigation aid and response to an unusual state immediately. It is necessary to develop an effective radar display. Method: Ten navy radar operators performed a series of trials in a low-fidelity radar simulation in which they attempted to solve the problems of current navigation situation. Results: The result demonstrated that the ecological interface's performance was better than the existing radar display on performance time and subjective mental workload. Conclusion: This study expand EID study field to navy ship radar display and confirm ecological display is better than existing radar display in performance time, subjective mental work load. Application: The result of this study may help to improve navy ship navigation radar display currently in use.

A prototype radar display unit was implemented using inexpensive off-the-shelf components, including a nonlinear estimation algorithm for the target tracking in a clutter environment. Two custom designed boards; an analog signal processing board and a DSP board, can be plugged into an expansion slot of a personal computer (PC) to form a maritime radar display unit. Our system provided all the functionality specified in the International Maritime Organization (IMO) resolution A422(XI). The analog signal processing board was used for A/D conversion as well as rain and sea clutter suppression. The main functions of the DSP board were scan conversion and video overlay operations. A host PC was used to run the tracking algorithm of targets in clutter, using the discrete-time Bayes optimal (nonlinear, and non-Gaussian) estimation method, and the graphic user interface (GUI) software for Automatic Radar Plotting Aid (ARPA). The proposed tracking method recursively found the entire probability density function of the target position and velocity by converting into linear convolution operations.

In VFR (visual flight rules) situations the pilot is responsible for collision avoidance. This can be problematic in case of high-speed business jets entering the vicinity of a local airport. Often, this airspace is occupied by slow, low-visibility aircraft like gliders, ultralight vehicles or, occasionally, balloons. These may be not equipped with active transponders. Thus, it is up to the pilot of the jet to take care of see-and-avoid separation.

Modern radar display based on commercial of-the-shelf hardware and custom software is developed. This paper describes the development process in detail — from a list of user requirements to a finalized product that passed the acceptance tests. In addition, we compared developed system with a similar commercially available product and we gave some hints on possible applications.

According to the theory of radar detector, a new advanced plane radar display terminal is presented in this paper. Based on the technologies of DSP and FPGA, the terminal possesses the functions of radar data acquisition, radar signal processing, the detected aims displaying, etc. The innovation of this paper locates that a high efficiency display method, named partial-screen-updating method, is designed and the comparison between the full-screen-updating method and the partial-screen-updating method in performance shows that the partial-screen-updating method has higher displaying performance than the full-screen-updating method in a radar detector.

We have implemented a prototype radar display unit using inexpensive off-the-shelf components. Two custom-designed boards; an analog signal processing board and a DSP board can be plugged into an expansion slot of a personal computer (PC) to form a maritime radar display unit.

The analog signal processing board is used for the A/D conversion as well as rain and sea clutter suppression. The main functions of the DSP board are the scan conversion and the video overlay operation. The host PC is used to run the multi-target decoupled /spl alpha/-/spl beta/ tracking filter and graphic user interface (GUI) software for an automatic radar plotting aid (ARPA).

A new scan conversion scheme and video memory architecture with advanced graphics for raster scan radar display are proposed in this paper. By taking advantage of a succession of radar range scans, the Cartesian coordinate increments (0 or 1) of every two axial adjacent points are pre-calculated and stored and then the Cartesian coordinates can be reconstructed by counting the increments in real time when converted. This new approach works quickly and precisely and can overcome artifacts in visual effects. The advanced graphics functions of this system greatly improve the display performance, especially the ability of plotting the extracted data. A practical display system based on these principles is developed and implemented. The excellent result proves its feasibility and versatility.

The authors describe a display processor unit (DPU) that develops display images for a multimode airborne radar system. The DPU described has a unique feature that allows display updates for a period of time when the radar is not transmitting. Once the radar image is formed, the information provided by the avionics system can reposition the display image. In this mode this aircraft is less vulnerable to detection by electronic counter measures. This feature also provides a significant improvement in display clarity during normal operation. The multimode airborne radar display modes, the equipment that generates the displays, and the technology used are also described. >

Summary form only given. As technology advances, equipment is becoming more compact, so the idea of having radar on a chip becomes more important. A radar system is broken down into its circuit elements. This system shows how we can have control of the minimum range detected by a software tool (LABVIEW) by simply moving a button instead of having complicated circuitry. A display system implemented fully with the same software that can be transformed into FPGA is also shown as a step towards having a radar system fully implemented on a chip. The use of software gives flexibility as it can be applied to any radar without the need to change any parameter in the display system.
