Detection performance comparison for wideband and narrowband radar in noise

The detection performance of wideband radars in noise is better than that of the narrowband radars under some conditions, due to higher range resolution and less target return fluctuation. The detection probabilities of wideband and narrowband radars for the wideband non-fluctuation, Rayleigh and Ricean target models in white Gaussian noise are deduced. The detection curves show that the wideband radars outperform the narrowband radars in detection performance in the case of high detection probabilities. But the detection predominance of the wideband radars is meaningless when the bandwidth of the radar is increased to a certain extent, because the integration loss of the wideband radar energy integration detector is increased with the increasing range resolution.
