The article explores the optimal selection of analog-to-digital converter (ADC) for radar phased array applications, examining trade-offs between dynamic range, sample rate, and direct current (DC) power consumption. It analyzes radio frequency (RF) to ADC cascade modeling to optimize system performance, explores the impact of varying RF and digital channel summation, and proposes system figures of merit for assessing performance normalized for DC power considerations.

The article discusses the use of radio frequency (RF)-to-analog-to-digital converter (ADC) cascade modeling for radar phased array applications. Topics discussed include the impact of RF and digital channel summation on dynamic range (linearity and noise) and DC power consumption, the Schreier and Walden ADC figures of merit, and the modeling of the RF front-end (RFFE), RF channel summation and ADC.

The article discusses the basics and advancements of X-band radar technology, highlighting its superior target resolution, smaller antenna size, and significant growth in the global radar industry. Topics discussed include the operational characteristics of X-band radar, key components and functions in radar system design, and the integration of individual discrete components to enhance system performance and ease of design.

This article debunks myths surrounding radar and highlights its importance in enabling intelligent IoT applications. Radar is not limited to aircraft and self-driving cars; it can be used in a wide range of IoT applications, from security monitoring to tracking small movements. Radar sensors provide more accurate and detailed information about objects, including size, speed, direction, and behavior. They can detect even small micro-movements and can be concealed within IoT devices. Radar is robust under different environmental conditions and operates across different frequencies. It consumes little power, making it suitable for battery-operated devices, and is being integrated into small devices like head-mounted displays. Radar has diverse applications, including human detection, presence/absence detection, tracking and localization, automatic door control, elder care, fall detection, vital signs monitoring, and HVAC and lighting efficiency. Overall, radar is a powerful and essential component of next-generation IoT applications that improve our lives in various ways. [Extracted from the article]

The article focuses on Lockheed Martin's contract to develop the Advanced Range Threat System Variant 3 (ARTS-V3) Variable Aperture Digital Radar (VADR) system for the U.S. Air Force, aimed at training aircrew to engage with advanced integrated air defense systems (IADS) by simulating long-range, high-power surface-to-air missile (SAM) radar threats. It highlights Lockheed Martin's role in enhancing aircrew training capabilities against modern threats.

The article discusses the increasing trend of legal system abuse as a driver of general liability claims in the construction sector. Factors such as social inflation, nuclear verdicts, and the devaluation of money contribute to inflated jury awards. The use of tactics like the Reptile Theory and third-party litigation funding also play a role in driving up costs. To mitigate this risk, businesses can implement good risk management practices, such as using security cameras to deter fraud and conducting thorough incident investigations. Regular claims review meetings and involving all stakeholders, including insurance carriers, can help identify high-cost claims and resolve them faster. [Extracted from the article]
