Doppler compensation in forward-looking STAP radar For air- and spaceborne MTI radar the clutter Doppler frequency depends on range for all array geometries other than linear sidelooking. This applies parti... O Kreyenkamp,R Klemm - 《Iee Proceedings Radar Sonar & Navigation》...
A doppler control circuit for a CW or pulse Doppler Radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several targets and to further provide a phase lock loop which tunes the radar to a particular target ...
Figure 10. Two-channel data extraction diagram. After combining the channel data, the process is carried out according to the procedure described in Section 3.1. The TDCM is used to estimate the channel phase error, and the results of the TDCM channel error estimation are shown in Figure 11...
The best frequencies are around 10 MHz, despite the channel being available until 20 MHz. Delay spread mean values are around 2 or 3 ms, with low deviation, and maximum Doppler spread values are around 0.7 Hz. All of this information is compared to Figure 17e,f, which shows the number ...

Doppler processing is routinely applied to isolate targets from noise, clutter and interference in conventional pulse-Doppler radar. If a target is co-located in range and azimuth and has a similar radial velocity (co-channel) as another target (or interference), that target may not be detected...
The invention relates to a method for estimating the Doppler frequency position of the main lobe clutter in two- or multi-channel pulse Doppler radar systems, in particular in synthetic aperture radar, characterized by the use of a pulse Doppler radar system equipped with a sum and a difference...
The method includes constructing an onboard MIMO radar clutter signal model and a target space time two-dimensional guide vector; utilizing Doppler filtering to conduct time domain dimension reduction processing on the echo data; resolving weight vectors formed by a space domain transmitting-receiving ...
