The topical issue of ultra-short pulse (USP) technology is introduce in the short-range radar, which should provide the performance of low-sized object detection against background reflections from the water surface with different excitement and grazing angles of vision. The paper reveals the measured reflection characteristics from water surface by using USP probing signal (PS) in radar systems for development and analysis of algorithm effectiveness.
The proposed solution is based on analysis of the experimental studies of USP radar at grazing angles of vision over the water of varying degrees of excitement. The experimental registration of digital arrays of radar images (RI) of water surface by using USP PS was realized. The data was obtained for the pulse duration being changed from 10 ns to 100 ns with the step equal to 20 ns.
The dependence of the estimate of radar cross section from the duration of PS at various azimuth vision angles of waves was obtained. Unknown property of USP radar technology consisting in providing the detection characteristics in inter-noise areas was revealed as it performs similar to free space in the immediate presence of the underlying water surface.
