摘要：

Signal or target detection is sometimes complicated by the presence of strong interference. When this interference occurs mainly in the sidelobes of the antenna pattern, a solution to this problem is realized through a sidelobe canceler (SLC) implementation. In addition, a system parameter of special importance in radar is the false-alarm probability. Therefore, an interference-canceling technique for radar application should maintain the false alarm probability constant over a wide range of incident interference power. With the requirements of sidelobe interference cancellation and constant false alarm rate (CFAR) a new algorithm for radar detection in the presence of sidelobe interference is developed from the generalized likelihood ratio test of Neyman–Pearson. In this development, the received interference is modeled as a nonstationary, but slowly varying Gaussian random process. Cancellation of this sidelobe interference is based upon a “synchronous” estimate of the spatial covariance of the interference for the range gate being tested. This algorithm provides a fixed false alarm rate and a fixed threshold which depend only upon the parameters of the algorithm. © 1990 IEEE
