Abstract

Abstract

For multisite radar system, to solve the data transmission rate problem, two kinds of Double Threshold Constant False Alarm Rate (DT-CFAR) detectors, the DT Generalized Likelihood Ratio Test (DT-GLRT) detector and the DT Adaptive Matched Filter (DT-AMF) detector, are proposed based on the GLRT and the AMF algorithms. Fisrt, the local test statistics which exceed the first threshold are transferred to the fusion center. Then, the global test statistic is obtained from the local test statistics and the final decision is made compared to the second threshold in the fusion center. The closed form expression for probabilities of false alarm and detection of the DT-AMF detector are also given when the Signal to Clutter plus Noise Ratios (SCNRs) are identical in the spatial diversity channels. Simulation results illustrate that the DT-CFAR detectors can maintain a good performance with a low communication rate.
