In the complex urban environment, echo signal of low-altitude, slow, and small target (LSS-target) is often submerged in strong clutter, it seriously mixed with slow clutter Doppler domain, resulting a serious decline detection performance radar. To solve this problem, LSS-target method suitable for environment proposed. proposed method, component suppressed through RELAX algorithm firstly, which notably reduces influence point source on weak detection. Then relatively long time set filter banks are chosen to realize coherent integration signal. Finally, CFAR based adaptive scene judgment carried out along range dimension each channel. Simulation experimental results verify effectiveness method.
