A STUDY OF GROUND CLUTTER USING A 10cm. SURVEILLANCE RADAR.
Abstract
The note reports on some results of a study of ground clutter at grazing incidence using a 10 cm. surveillance radar. The digitized amplitudes of the clutter signals are processed in a computer to produce probability distributions of the clutter radar cross-section in dB w.r.t. 1 square meter. A clutter map of the area of interest describing the clutter echo in terms of the median cross-section and interquartile range of each resolution cell has been made. Echoes from individual resolution cells within the area have probability distributions that fit well known mathematical expressions. Probability distributions of clutter cross-section fluctuations with a rotating aerial operating at two different pulse lengths (10:1) have been computed and show a cross-section difference of between 18dB and 22dB for the same probability compared with the predicted 10 dB. An explanation for this is given by postulating a non-uniform spatial distribution of clutter. (Author)
