Bistatic MIMO Radar with Unsynchronized Arrays

Abstract

This paper presents a method for enabling bistatic radar under time synchronization offsets. Multiple transmitters and receivers are used to provide direction of arrival and departure measurements. These provide the receivers sufficient diversity to estimate the target locations and timing offsets from the target lists. The signal processing is presented and the parameter estimation is formulated as a non-linear least squares problem. The performance is validated numerically where we show nanosecond accurate synchronization.
