Target Motion and High Range Resolution Profile Generation

The problem of forming high range resolution (HRR) profiles from radar data of moving targetsis considered. HRR profiles can result from processing range-Doppler images of targets, whereby the 2-D range-Doppler image is collapsed into a 1-D range profile. The interest in HRR profiles can partly be explained by the hypothesis that they can be used to characterize and discriminate targets. HRR profiles are also of interest because of their potential to be less sensitive than range-Doppler images to target motion. Two different approaches to forming an HRR profile from a range-Doppler image of a moving target are examined. The advantages and disadvantages of each approach are discussed. Results are obtained through analysis, simulation, and an example with synthetic aperture radar (SAR) data.
