雷达信号处理雷达信号处理radar signal processingleida xinhao ehuli雷达信号处理(radar signaz proees、ing)对雷达接收机输出的视频信号进行滤波、检测和估值的过程。按信号形式分，有模拟信号处理、数字信号处理和模一数结合的信号处理等类型。不同体制的雷达有不同的信号处理方法。雷达信一号处理中的滤波是抑制杂波，提高“信号电平”与“杂波加噪声电平”之间的比值。检测是区分接收机的输出信号中有无目标回波。区分的方法是按预定的发现概率和虚警概率设置一个门限电平，超过此电平的信号认为是存在目标回波。检测后的回波信号还可在多个重复周期内进行积累(相加)，以进一步提高目标回波信号与噪声电平的比值。估值是从检测出的回波信号中提取目标的多种信息，如测定目标的方位、距离、高度和速度等数据。人工操作的雷达信号处理器，只具有滤波和部分的积累功能，其余的积累功能以及门限检测、数据估值等功能则由操纵人员在显示器上进行。自动或半自动的雷达信号处理器一般由数字器件组成，具有上述全部功能，其输出的目标数字化数据送到雷达显示器上显示，同时通过数据通信链路传送到上级指挥中心和有关作战单位。(尚志祥)
