Figure 1From: Analysis of Approximations and Aperture Distortion for 3D Migration of Bistatic Radar Data with the Two-Step ApproachTravel time error [ns] for the rms approximation (a) and for the LLNL approximation (b) as a function of (target depth) and (lateral distance of the antenna from the vertical above the target). The system is monostatic. The antenna-medium distance is 10 cm, and the radar wave velocity into the medium is 12 cm/ns.Back to article page
