To analyze the positioning accuracy of different MTMR systems, we use two-dimensional positioning GDOP analysis method to simulate the systems of two-transmit two-receive, transmit four-receive and three-transmit three-receive (2T2R,2T4R,3T3R).The results show that: two-conl一 pared with the 2T2R,the ment much more obviously positioning accuracy of the 2T4R system is overall improved and the improve-in the near baseline zone:the 3T3R overcomes the defects of the 2T2R that has positioning blind zone on the baseline gion tion rounded by the results provide three stations is ',however,compared with the not obviously improved except 2T4R,positioning accuracy of the re-in the near baseline zone. The simula-theoretical reference in MTMR detection system selection and radar station deploy-ment,and thus is valuable to radar configuration applications. 5 O7 G! A( }4 E) }" v' a% u
