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.

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.

WebJan 1, 2003 · The Doppler frequency for bistatic configuration can be represented as the bistatic range rate normalized by the wavelength of the carrier signal over time [14]. ... The radial velocity or line-of-sight velocity, also known as radial speed or range rate, of a target with respect to an observer is the rate of change of the distance or range between the two points. It is equivalent to the vector projection of the target-observer relative velocity onto the relative direction connecting the two points. In astronomy, the point is usually taken to be the observer on Earth, so the radial velocity then denotes the speed with which the object moves away from the Earth (or …
