Matrix Constant False Alarm Rate(MCFAR) Detector Based on Information Geometry
With the development of signal processing technology,many new requirements are put forward for radar target detection.For instance,it should accurately detect the targets in perturbed environment and with small bunch of pulses.However,in the situation of a few number of pulses the classical methods using coherent accumulation are not very satisfactory.In order to overcome the drawbacks,a lot of new mathematical methods were introduced.Information geometry method is one of these methods which researches statistical problems on the manifold and metric space,and it provides us a new method to enhance radar detection performance.Based on the method of information geometry and Constant False Alarm Rate (CFAR)detector,the paper introduces a new detection structure called Matrix Constant False Alarm Rate (MCFAR) DETECTOR to detect targets for Pulse Doppler radar with small bunch of pulses.The paper also simulates the feasibility of MCFAR DETECTOR and compare the performance with classical method.Results show that the MCFAR DETECTOR can accurately detect the targets and improve the detection performance.
