基于統(tǒng)計特性差異的距離多假目標識別技術(shù)
[Abstract]:A deception jamming recognition method for radar range multiple false targets based on the difference of statistical characteristics of angle measurement is proposed in this paper. First of all, it is easy to misjudge multiple real targets in the same angle resolution cell as multiple false targets in distance by the traditional angle measurement chi-square test method, which is easy to be misjudged by the traditional angle measurement chi-square test method. Based on the fact that the mean value of the distance measurement difference between the false target and the real target is usually a time-invariant constant, the angle measurement chi-square test and the joint test of the distance difference mean and variance are combined. The accurate discrimination of the existence of interference between multiple false targets is realized. Then the multi-time measurement is accumulated, and then the sample set is constructed by the error of the corresponding angle measurement at the corresponding time. Finally, the accurate identification of true-false targets is realized by using the method of clustering and dividing the variance of false targets, which is larger than that of real targets' angular measurement and the method of cluster division of measured variances is adopted to distinguish the true-false targets.
