A detection algorithm for radar weak targets under the interference of strong targets
In radar multi-target detection, the weak target might be interfered by the near strong target, which badly influences the detection of weak target. A novel detection algorithm for weak targets is proposed to cope with the situation above. Combining the Keystone transform and the Least Square (LS) filter, the return of strong target is reconstructed and then removed from the original. Finally, the weak target is detected by integration for the residual. The effectiveness of the proposed algorithm is illustrated and analyzed by simulations.
