摘    要:为解决ESM与雷达异类传感器的航迹关联问题,基于统计信号分析理论,采用最大似然估计准则,给出了利用ESM与雷达角度测量信息在航迹互联先验概率相等情况下的航迹关联判别函数.同时给出ESM与雷达航迹由等数量观测构成情况下的错误关联概率表达式.最后,由错误关联概率曲线得出了采取减小雷达航迹测量误差与ESM航迹测量误差比值和增加测量次数等措施可以减小错误关联概率的结论.

Abstract:In order to solve the problem of ESMradar track correlation,by using the rule of maximum likelihood estimation based on statistical signal analysis theory,the track correlation discriminant function is presented for the condition that the azimuth measurements of ESM and radar have the equal prior probability.The expressions of probability of falsely associated ESM-radar track is also presented with the same number measurements.The conclusion is that the probability of ESM-radar track false association can be decrease by 1) decreasing the ratio of azimuth measurement error of radar with that of ESM,and 2) increasing measurement times.
Keywords:data fusion  Electronic Support Measures(ESM)  track correlation
