Pre-Doppler direct data domain approach to STAP In the direct data domain (D3) approach to space-time adaptive processing, the data corresponding to each range cell is processed individually for interrog... D Madurasinghe,Berry, PE - 《Signal Processing》 被引量: 13发表: 2005年 ...
Continuous wave direct-conversion microwave Doppler radar can be used to detect cardiopulmonary activity at a distance. Demodulation sensitivity to a target's distance in a single channel system can be solved by using a quadrature direct... A Vergara,VM Lubecke,Anders Hst-Madsen 被引量: 13发表...

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...
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...
