Abstract

Abstract:

To decrease the data transmission rate between fusion center and local radar stations for target detection in distributed multi-input multi-output (MIMO) radar, a double-threshold generalized likelihood ratio test (DT-GLRT) constant false alarm rate algorithm is proposed. Firstly, local GLRT test statistics are censored through the first threshold and the over-threshold local test statistics are transferred to the fusion center. Secondly, the transferred data are fused to decide the target presence according to the second threshold in the fusion center. The closed-form expression for the probability of false alarm of the DT-GLRT is derived. Simulation results demonstrate that the proposed DT-GLRT algorithm can maintain good detection performance with a low data transmission rate.

Key words: distributed MIMO radar, constant false alarm rate, double-threshold detection, generalized likelihood ratio test
