Abstract
An investigation is made of methods of averaging millimeter-wave (MMW) polarimetric data for subsequent target-identification/discrimination processing. The averaging is required because the radar cross-sections (RCSs) of the target vehicles, which rotate during the measurements, change rapidly with azimuth angle. The RCS in an individual polarimetric transmit-receive channel, the difference between the RCS in two channels, and the difference between the phase of the signals in two channels are subjected to averaging processes both in azimuth angle and radar-frequency spaces. The averages over the 640-MHz bandwidth of the radar are found to be significantly more effective in minimizing the mean spread in these quantities in a 1-deg scan than the averages of single-frequency data over a number of smaller-angle scans. Frequency averaging typically reduces the standard deviation in the measurements during a 1-deg scan of a complex target.
