Abstract
The ω-k synthetic aperture radar (SAR) algorithm is a computationally efficient algorithm for near field three-dimensional (3D) monostatic SAR imaging in nondestructive testing applications. However, bistatic measurements are preferred in order to obtain high dynamic range, in particular when real-time imaging arrays are used. This paper investigates the image distortion caused by using an equivalent monostatic imaging algorithm for bistatic measurements. Simulation and measurement at millimeter wave frequencies in Ka-band (26.5-40 GHz) are used to investigate the resultant image distortion. Further, the image distortion is quantified through root-mean-square (RMS) error which is calculated as a function of bistatic transmitter-receiver separation distance, range and noise power.
