Doppler Blind Zone Analysis for Ground Target Tracking …

WebJan 23, 2024 · A bistatic range measurement can locate a target at an ellipsoid in 3-D Cartesian coordinates, but for the intersection of two ellipsoids, which is an ellipse, a third bistatic range measurement is necessary to possibly locate the target, resulting in the generation of multiple ghosts. WebThe width of the bistatic Doppler blind zone in the bistatic range-rate domain is described by the minimum detectable velocity (MDV). It is determined by the half-width of the notch in the IF distribution at 3dB for a given azimuth look direction. An exemplary 1D-IF distribution at a ﬁxed look angle is shown in Fig. 3. granite publications texas

Web摘要： The focusing of bistatic synthetic aperture radar (BiSAR) data is more challenging than the traditional monostatic counterparts because of the strong range-azimuth coupling of echo signal, and the range cell migration (RCM) and Doppler frequency modulation (FM) rate, which are caused by complex geometric configuration.

WebA range bias means that measured ranges are greater than the line-of-sight range to the target. Elevation bias means that the measured elevations are above their true elevations. Biases are larger when the line-of-sight path between the radar and target passes through lower altitudes because the atmosphere is thicker at these altitudes.
