Abstract:
This letter designs a source number estimator based on rank test method and applies it to solve the problem of extended target scattering center number estimation in radar detection. Considering the distribution difference between target and noise, the estimator is designed by combining the modified rank test with enumeration principle. The estimator is further improved by adding a secondary screening procedure. Performance of the estimator is assessed by comparison with a typical source number estimation scheme. Simulation results show the robust performance of the proposed estimator which approaches the optimal and is superior in low-density distribution scenarios.
