引 言 飞行器雷达成象系统的基本任务是获取观测反射能力的估计G(r_0)(r_0确定目标单元的坐标)。当由飞行器的雷达反射信号获得这一估计时,数学运算的内容和顺序就决定了处理的算法。算法的结构与各种因素有关,其中主要因素是相对于雷达和飞行器的运行特性、雷达结构、要求的分辨率以及探测信号的形式和参数等等。 Introduction The basic task of an aircraft radar imaging system is to obtain an estimate G (r_0) of observed reflectivity (r_0 to determine the coordinates of the target cell). When this estimate is obtained from the radar reflection of the aircraft, the content and order of the math operations determine the algorithm to be processed. The structure of the algorithm is related to various factors, of which the main factors are relative to the operational characteristics of the radar and the aircraft, the radar structure, the required resolution and the form and parameters of the detection signal, and so on.
