%X Wideband radars have higher range resolution than narrowband radars, and the target fluctuation is less. The wideband and narrowband returns of the wideband non-fluctuation target model, the wideband Rayleigh target model and the wideband Ricean target model are analyzed, and the detection probabilities of them in white Gaussian noise are deduced. The detection curves show that the wideband radars outperform the narrowband radars in the case of high detection probabilities; but the integration loss of the wideband radar energy integration detector is increased with the increasing of the wideband radar range resolution, and this factor causes that the detection predominance of the wideband radars to the narrowband radars is meaningless when the bandwidth of the radar is increased to a certain extent.
