基于多重频脉冲串信号解速度模糊的研究

Research on Velocity Ambiguity Resolution for Multiple PRF Radar

针对双重频解速度模糊系统中,信号参数选择不合理导致解速度模糊存在量化误差的问题,推导了双重频解速度模糊的量化要求。为了增大最大不模糊速度,该文提出多层解模糊系统,提出了一种四重频脉冲串解速度模糊的模型,推导了四重频信号脉冲个数的下界,并简化为了三重频脉冲串信号模型。仿真验证了理论推导的正确性。

In dual pulse repetition frequencies radar systems, mathematical deduction of the number of pulse repetition intervals required to satisfy quantitative requirements is presented to resolve velocity ambiguity. Multiple layer systems to increase the maximum unambiguous velocity are proposed. A new model of quadruple pulse repetition frequencies signal is proposed. The lower bound of the number of pulse repetition intervals required to satisfy quantitative requirements is deduced and quadruple pulse repetition frequencies signal is simplified as triplet pulse repetition frequencies signal. Simulation results validate the accuracy of our deduction.
