WebbThe range resolution, which is a parameter for accurately detecting an object in the FMCW radar system, depends on the modulation bandwidth. Expensive radars have a large modulation bandwidth, use the band above 77 GHz, … WebbIf only the 3D millimeter wave holographic algorithm were to be used to reconstruct the continuous range distribution, it would not be accurately restored. Therefore, the range-to-resolution improvement algorithm proposed in this paper was used.
Webb20 nov. 2024 · We choose an FMCW radar to measure the WSAW, as such radars have unique advantages that are not available in other radar types. Those are: High precision: Since the micro-amplitude changes on the water surface are in the order of micrometers, a terahertz-level bandwidth is required to directly measure the distance changes caused … WebbIEEE 8 lutego 2024. This paper presents a novel, small, and compact K-band synthetic aperture radar (SAR) system – based in an unmanned aerial vehicle (UAV) – together with the first drone-based experiment results. The article also describes the system architecture and the implemented SAR imaging algorithm.
