METHOD AND RADAR SYSTEM FOR CLUTTER FILTERING OF BROADBAND RADAR SIGNALS

摘要

A method is disclosed for creating a tool for clutter filtering of broadband radar signals by obtaining a measure of the impedance of an echo target. A distance resolution is selected and then a power spectrum is calculated for the necessary transmitting signal. Further a target area profile ρ(b) is estimated by utilising a correlation between the radiated signal and the received signal in form of a convolution. The target impedance is then calculated and thereafter, by means of the achieved impedance characterising the echo of the target, the target can be filtered out.
