摘　　要：多发多收是提高雷达系统定位精度的重要手段之一,为分析不同形式多发多收定位精度,采用二维定位几何精度稀释分析方法,分别针对两发两收、两发四收和三发三收三种探测方式进行了仿真分析.结果表明:两发四收探测系统定位精度比两发两收系统整体上提高,在基线近区提高比较明显;三发三收探测系统克服了两发两收探测系统在基线上定位盲区的缺点,但与两发四收探测系统相比,除基线附近外,在三站围成的定位区域内定位性能并没有明显提高.仿真结果为多发多收探测系统选取、布站提供了理论参考,具有一定的工程应用价值.Multi-transmit multi-receive（MTMR）is an important mean to improve the positioning accuracy of the radar system.To analyze the positioning accuracy of different MTMR systems,we use twodimensional positioning GDOP analysis method to simulate the systems of two-transmit two-receive,twotransmit four-receive and three-transmit three-receive（2T2R,2T4 R,3T3R）.The results show that：compared with the 2T2 R,the positioning accuracy of the 2T4 Rsystem is overall improved and the improvement much more obviously in the near baseline zone;the 3T3 Rovercomes the defects of the 2T2 Rthat has positioning blind zone on the baseline,however,compared with the 2T4 R,positioning accuracy of the region rounded by the three stations is not obviously improved except in the near baseline zone.The simulation results provide theoretical reference in MTMR detection system selection and radar station deployment,and thus is valuable to radar configuration applications.
