Figure 3From: Analysis of Approximations and Aperture Distortion for 3D Migration of Bistatic Radar Data with the Two-Step ApproachMigration aperture with the one-step approach for the rms and the LLNL approximations at four different target depths. The antenna-medium distance is 10 cm; the radar wave velocity into the medium is 12 cm/ns; the TX-RX distance is 14 cm with the azimuth oriented in the -direction. A small distortion of the circular shape is observed on the migration aperture as a result of the TX-RX separation.Back to article page
