Abstract With reference to the air target detected by ultra-wideband(UWB)/impulse radar,this paper discussed transient signal processing techniques.In weak UWB signal detection,wavelet transforms and high order spectrum estimation were preferred.In target characteristics analysis,a time domain bispectrum estimation algorithm was presented,which could estimate accurately local scattering distribution of complex target.A free field experimental impulse radar system was introduced in this paper.With this system,the response of several canonical target models and scale aircraft were measured and processed.
