An approach to detecting the targets of aircraft and ship together by over-the-horizon radar

The paper discusses the selection of over-the-horizon radar (OTHR) parameters for detecting aircraft and ship separately. Then, a method of detecting a high-flying target (i.e., aircraft) and a slow-speed target (i.e., ship) in parallel by OTHR is presented. The combination of range-Doppler 2-dimensional CFAR and superresolution techniques is the main problem in the process of detection. Simulation results of real (OTHR) data demonstrate the efficiency of the proposed method.
