摘要

摘要: 该文针对距离模糊情况下机载双基地雷达杂波抑制难题，提出一种利用几何配置减轻距离模糊影响的方法。首先，利用任意双基配置下的杂波模型来分析距离模糊的影响；其次，建立机载双基地雷达杂波等距离环模型，分析几何配置与距离模糊的关系；最后，求解最大不模糊脉冲重复频率。仿真结果表明：距离模糊使得机载双基STAP杂波抑制性能严重下降；选择合适的双基配置能够有效减轻距离模糊的影响。仿真实验验证了所提方法的有效性

Abstract: In this paper, we study the clutter suppression problem of an airborne bistatic radar with range ambiguity and propose a novel method to reduce the impact of range ambiguity using geometric configuration. First, a clutter model, under any bistatic configuration is used to analyze the impact of range ambiguity. Second, a clutter equal-distance ring model of the airborne bistatic radar is established, and the relation between the geometric configuration and range ambiguity is analyzed. Third, the maximum pulse repetition frequency required to avoid range ambiguity is calculated. Simulation results show that the clutter suppression performance of an airborne bistatic STAP is greatly diminished with range ambiguity; however, this impact can effectively be reduced by selecting the appropriate radar configuration. Finally, simulation is performed to validate tests its validity.
