According to the application requirements of reconnaissance and jamming integration in the field of electronic countermeasures and the operational requirements of wide and narrow band radar, a dual-mode reconnaissance and jamming integration architecture based on digital transceiver channelization and digital parallel up-down conversion structure is proposed in this paper. The implementation of transceiver based on 50% overlapping channel overlap without blind area is studied; and simulation model is established and is ability to reconstruct wide and narrow band signals is evaluated. On this basis, the strategy and basis of the two modes working together are obtained. Through dual-mode cooperative work, it cannot only measure the parameters of signals with different bandwidth, but also adaptively store digital radio frequency and reconstruct jamming signals with high linearity and low spurious.

In order to analyze the cause and influence factors of the torsional vibration of the dual mode multistage gear transmission， a hybrid electric vehicle dynamic model is established based on SIMPACK. By means of imposed excitation on the dynamics model and set output channel on it， a simulation system for torsional vibration is constructed. The vibration mode of transmission is analyzed as a torsional vibration simulation system， and is validated by the results of theoretical calculation and experimentation， which verified the effectiveness of the established simulation system. On this basis， some objective parameters， such as stiffness and damping of torsional damper， are analyzed for the effect of dampen vibration. The result shows that it has a good effect on the attenuation of torsional vibration in certain frequency through adjustments to characteristic parameters of torsional damper in a proper range.

Color-guided depth super resolution is one way for improving the quality or resolution of the low resolution depth image, which utilizes an additional aligned high-resolution color image as assistance. However, if the smooth regions have rich color texture or the color edges do not align well with the depth edges, artifacts including texture copying and edge blurring may occur. In view of these artifacts, the paper proposed a novel dual mode joint trilateral filter（DMJTF） method for color-guided depth map super resolution. This method built an edge image pyramid dictionary by a single low-resolution depth image, and then got a high-resolution edge image by constructing a MRF model. It used the edge map as a guidance to decide when to change the filter mode, one mode was for the pixels on the edges, and the other was for the pixels in the smooth regions. Experimental results in both qualitative and quantitative aspects demonstrate the effectiveness of our approach over prior depth map upsampling works,which alleviates artifacts introduced by color image and preserves sharp edges well.

In order to solve the problem that most cyclic ADCs can not implement dual input modes, a 10-bit cyclic ADC with single-ended input mode and differential input mode is proposed in this paper. By using RSD algorithm, the threshold deviation of comparators is corrected. And improved operational amplifier structure with two-stage self-compensation and gain boosted is proposed, which can achieve high gain and ensures that the output result is not affected by loop offset. Simulation results show that the proposed cyclic ADC has a conversion speed of 200 ksps under a 5.2 MHz working clock and 2.5 V supply, the signal to noise ratio is 60.98dB, the effective number of bits is 9.8 bit, the power dissipation is 4.97 mW, and the layout area is 0.059 mm2. The research conclusion indicates that the circuit has relatively high conversion speed and precision, and the applicability of the circuit is extended due to the dual input modes.
