Bistatic range rate
Webbistatic range-rate as determined via the Doppler effect. Clutter contacts in this scenario had an observed range-rate that was uniformly distributed between ± 12.2 m/s with the exception of a narrow gap between ± 1.5 m/s. Target contacts had an observed range-rate between ± 3.5 m/s with a similar gap between ± 1.5 m/s. WebAbstract: This letter investigates the problem of locating a moving target using bistatic range (BR) and bistatic range rate (BRR) measurements in multi-input and multi-output (MIMO) radar systems.

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. 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.
