PERFORMANCE ANALYSIS OF DISTRIBUTED OS-CFAR DETECTION WITH NONCOHERENT INTEGRATION OF MULTIPLE PULSES

This paper analyzes the distributed OS-CFAR detection with noncoherent integration of multiple pulses under the conditions of nonhomogeneous background and two local detectors.Compared with the monopulse detection and the single sensor detector and the corresponding optimal fixed threshold detection,the integration of multiple pulses improves the distributed detection obviously,and the increase of number of integrated pulses reduces its difference from the optimal fixed threshold detection.Although the increase of number of integrated pulses weaken the superority of distributed detection over the single sensor detection,the superority still exist and it is more obvious for low SNR.
