Effects of Polarization and Resolution on the Performance of a SAR AutomaticTarget Recognition System

摘要

This article summarizes a study in which data collected by the Lincoln Laboratory33-GHz SAR were used to perform a comprehensive comparison of automatic target recognition (ATR) performance for several combinations of polarization and resolution. The Lincoln Laboratory baseline ATR algorithm suite was used, and it was optimized for each polarization/resolution case. The polarizations evaluated were HH and PWF; the resolutions evaluated were 1 ft x 1 ft and 1 m X 1 m. The data set used for this study contained approximately 74 sq km of clutter (56 sq km of mixed clutter and 18 sq km of highly cultural clutter) and 136 tactical target images divided equally between tanks and howitzers.
