Ultrawideband (UWB) technology has many advantages compared to its narrowband counterpart in many applications. We present a new compact low-cost UWB radar for indoor and through-wall scenario. The focus of the paper is on the development of the signal processing algorithms for ranging and tracking, taking into account the particular properties of the UWB CMOS transceiver and the radiation characteristics of the antennas. Theoretical analysis for the algorithms and their evaluations by measurements are presented in the paper. The ranging resolution of this UWB radar has achieved 1-2 mm RMS accuracy for a moving target in indoor environment over a short range, and Kalman tracking algorithm functions well for the through-wall detection.

The low altitude breakthrough has become an important battle mode of modern war, which brings the huge difficulty for low altitude defense. The microwave technology is an effective method to detect the moving target in the low altitude. Taking the frequency modulation of microwave as basic principle, and combined the Doppler Effect which can measure the velocity information of target, a microwave detecting system based on twice mixing is established. Its composition and working principle are analyzed, and the circuits are designed. The laboratory experiment indicates that it is completely feasible to apply the system to the detection of the moving target.
