摘要

While traveling, the traveling detection pulse radar cannot capture the accurate target information through signal process, owing to the Doppler effect. To solve the problem, this paper attempts to design a proper compensation method into signal processing to correct the Doppler information of the target. Specifically, the existing signal processing algorithms of pulse radar were reviewed in details, namely, pulse compression, moving target detection (MTD) and constant false alarm rate (CFAR) detection). Based on the MTD and CFAR and considering the requirements of 3D geographic scene, the author developed a real-time calculation method of radar 3D detection range and 2D slice at specified altitude under terrain shading factor. After determining the target nature by the radar signals, the corresponding 3D model was adopted to realize a realistic display of the target, which verifies the effectiveness of the proposed method.
