摘要：

For the issue that the range spread targets got from the wideband radar signal are difficult to integrate for detect by the large velocity of target, a Hough Transformation Detector (HTD) is developed. Adjoin high resolution radar range profiles of range spread target processes high correlation coefficient. Using this characteristic, signal energy integrated by Hough transformation in cross-correlation order and correlation time two dimensional plane and target detect are carried. Theory analysis show HTD is non-dependent on target scatter distribution information and target moving information and processes Constant False Alarm Ratio (CFAR) performance. Computer simulation experiment show HTD achieves better detection performance than Non-Scatterer Density Dependent Generalized Likelihood Ratio Test (NSDD-GLRT) detector. ©, 2015, Science Press.
