摘要
脉冲多普勒雷达在信号检测时存在距离模糊和速度模糊的问题。为了解决模糊问题 ,在体制上雷达一般采用多重PRT(脉冲重复周期 )工作方式 ,采用这种体制的雷达在信号处理上 ,又有多种解模糊算法。简要描述了采用余差查表法解距离模糊的原理及实现的相应步骤 ,分析了该算法在系统存在测量误差情况下的容错性 ,并通过大量的仿真证实了分析结果。
There exist ambiguities of range and velocity in the signal detection of pulse Doppler radar. To resolve the ambiguities, a multiple pulse repetition frequency system is used in the radar, and several methods for resolving the ambiguities are adopted in this system. This paper describes the principle of ambiguity resolving using residues' difference look-up table and the implementation steps. The error tolerance of the algorithm in the presence of measurement error is analyzed, which is proved by numerous simulations. At the end of the paper, the simulation results are presented.
