Bistatic range rate
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. WebThe radar geometry defined by a spatially separated transmitter and receiver with a moving object crossing the baseline is considered as a Bistatic Forward Inverse Synthetic Aperture Radar (BFISAR). As a transmitter of opportunity, a Digital Video Broadcast-Terrestrial (DVB-T) television station emitting DVB-T waveforms was used. A system of vector equations …

WebApr 1, 2024 · Tracking with bistatic radar measurements is challenging due to the fact that the measurements are nonlinear functions of the Cartesian state. The converted measurement Kalman filter (CMKF)... Webthe bistatic range-rate resolution is given by r_ = c=f cT, where f c is the radar center frequency, and Tis the coherent pulse interval. The collection of measurements is the matrix z(t;r) = 0 @ z 11 z 1N D z N r1 z N rN D 1 A; (1) where N d and N r are the number of range and range-rate bins.
WebDec 1, 2016 · Next, the two successive bistatic range measurements can be used to estimate the instantaneous range-rate of the target, which is commonly referred to as the target ‘Doppler’. First, recall that gives the time interval δτ t, n between these two successive bistatic range measurements indexed by n and {n + 1}.
