- Abstract
To solve the problem of multi-scattering dots during high resolution radar tracking extended targets, a radar target dot processing method is proposed based on joint probabilistic weighting technique. Firstly, remained variables of the detected multi-scattering dots are constructed. According to judgment rule for target dot partnership processing, abnormity scattering dots are eliminated. And then, scattering dot position and echo amplitude are considered to calculate the joint probabilistic weighted value and scattering center is estimated by target multi-scattering dots weighted fusion. Simulation results show that the method can efficiently restrain clutter in high resolution radar tracking extended target dot processing, and the estimation precision is improved 20. 63%,47. 51% and 41. 03% in range, azimuth and pitch, respectively. The method is reliable and meets engineering requirement.
