Angular Discrimination Using Multistatic Pulse Radar Information
Abstract
Time of arrival and differential delay of short pulses measured by several receivers, arranged to form a one-dimensional, linear array, can be used to determine distance and lateral position of objects. This technique is combined with the concepts of wavefront reconstruction, where the phase information is evaluated in order to recover the angular direction of incident wavefronts. Simulation results are given for an eight receiver system, indicating resolution and remaining ambiguity for two dimensions. The system is intended to be applied to microwave imaging purposes, where high angular and radial resolution have to be obtained in order to enable object identification.
