A polarisation approach to the clutter problem
Abstract
The potential of applying a wave polarization technique to the problem of clutter in radar systems is discussed analytically and experimentally. The analytical work is based on the approach of Gent et al. (1963) noting the behavior of the target to the general EM wave as characterized by three echoing lengths and three phases. In the experimental work, an S654 H radar and a twin-beam 23-cm surveillance radar were used. The logarithmic video signal was used and the amplitude of each resolution cell was recorded digitally on magnetic tape. Overall radar performance on each polarization mode (linear accept and reject, circular accept and reject) was measured by balloon tests. Results are presented for rain echo cumulative distributions, bird echo cumulative distribution, and the backscattering coefficient.
