An Analysis of Factors Influencing the Angle Measurement Performance on Guidance Radar

制导雷达性能影响因素分析研究能为制导雷达性能评估、设计开发、技术改进提供有力的技术指导。对特定背景下制导雷达角度测量性能影响因素进行了系统、综合的研究,将影响制导雷达角度测量性能的众多因素归纳为内部、外部和中间三个层面,主要分析了目标、杂波和制导雷达平台运动因素对性能的影响,得出了在通常制导雷达系统参数下,径向加速度的影响可以忽略;目标RCS起伏对性能影响不大,距离单元内含多个强散射中心的目标对性能影响大;杂波反射率越强、杂波幅度起伏越大、杂波相关性越强对性能影响越大的结论,通过仿真实验验证了结论的正确性。

An analysis of factors influencing the angle measurement performance on guidance radar can provide strong technical guidance on radar performance evaluation,design and development,technical improvement.In this paper,the specific background of factors affecting the radar angle measurement was studied systemically and comprehensively,and the factors were summarized as internal,external,middle levels.The influences of target,clutter and guidance radar platform motion factors on angle measurement performance were analyzed,and the conclusion was reached as follow： the radial acceleration can be ignored under the usual guidance radar system parameters;Target RCS fluctuation has little effect on performance,the range bin of strong multi-scattering center impacts on performance greatly;The stronger reflectivity,the larger the clutter＇s reflection ratio,amplitude fluctuation and correlation are,the greater the influence on performance is.The simulation results validate the correctness of the conclusion.
