具有非相参积累的双门限CA—CFAR检测器

The Dual Threshold CA-CFAR Detector with Noncoherent Integration

介绍了一种采用伪随机码调相连续波的相控阵实验雷达的检测器．它将一般ＣＦＡＲ检测方法的纯理论性与实际数字系统实时处理的要求相结合．在检测性能上，它能依概率识别和对付数目可变的干扰目标．在没有干扰目标时，它的性能与独立、同分布噪声环境下的ＣＡ—ＣＦＡＲ检测器性能相同；当有干扰目标时，它的性能将明显优于单门限ＣＡ—ＣＦＡＲ检测器。

This paper introduces a kind of CA-CFAR detector, which is a equipment for PRC-Phase Controlled-CW radar. Combining the detecting theory of the general CFAR with the real time processing of practical digital systems it can resolve interfering targets with different numbers by probability. Its performances are same as CA-CFAR detector without interfering targets, however, in presence of interfering targets, are obviously superior to simple threshold CA-CFAR detector.
