CLEAN Removal of Ground Clutter in Mobile Passive Radar

The paper is focused on Doppler-spread clutter removal in mobile passive radar. The presented algorithm is based on CLEAN technique, which was developed for radio astronomy, but is commonly used for passive radar. The algorithm was designed for application in a passive radar placed on a moving platform and equipped with an array antenna system for surveillance signal reception. The use of multielement antenna allows for the application of a space-time approach for modeling the clutter signal to be used, followed by clutter removal using modeled multichannel signal. In the paper theoretical considerations are accompanied by the results of simulations.
