Receiver design for MIMO tracking radar

Abstract

The paper is the first in a series of three which address the problem of radar transmitter and receiver design for MIMO (multiple transmit and receive antennae) tracking systems. This paper considers the receiver design problem. The method described consists of a generalised matched filter receiver which produces approximate maximum likelihood estimates of the target's delay and doppler, and the spatial wavenumber (angle of arrival) and its time derivative. The paper argues that this approach is novel in the sense that it appropriately combines the usual single antenna matched filter receiver, and the beamforming required for the multiple antenna case. Simulation results are used to assess the performance of the proposed method.
