脉冲多普勒-阶梯跳频信号混合设计与处理技术的研究

Research on Pulse Doppler & Step Frequency Waveform Complex Design and Processing

本文提出了一种混合信号设计新方法，在雷达自身存在较高的运动速度情况下，采用多普勒速度分辨——速度补偿——高分辨距离成像的准二维信号处理技术，可一次性完成目标的速度测量、速度匹配和距离测量。同时，由于混合信号处理具有速度和距离两重分辨能力，故在多目标环境中可以有效地进行目标识别和捕获。最后还给出了信号波形的设计考虑与约束条件。

This paper presents a new design method of complex radar signal. As a constant higher Doppler speed component exists in the returned signal caused by radar moving, it can make a measurement of target's speed, speed matching and range measuring at the same time by employing the quasi two dimension signal processing of Doppler transform and high range resolution imaging with the speed compensation. Due to the achievement of both speed and range resolutions in signal processing, it may be convenient to make a target identification and acquisition in the circumstances of multi targets. Finally, the considerations and constraints about the complex signal design are discussed.
