TY  - JOUR
AB  - Estimating the parameters of multiple closely-spaced targets is a key topic in MIMO radar research. The key to designing and analysing an array system in general lies in understanding the array manifold, which completely charac- terises the geometry of the array system. The shape of the array manifold has a profound and fundamental importance and has been extensively investigated in the literature using differential geometry. However, until now, these methods have been applied only to the receiver array of the array system. Therefore, in MIMO radar (where there also exists an arrayed transmitter), it has not previously been possible to fully characterise the whole transmit-receive system geometry within such a framework. In this paper, an equivalent ‘virtual’ SIMO (Single Input Multiple Output) representation of the MIMO radar system is established which allows direct analysis of the full MIMO system geometry. By analysing the virtual array manifold, it is shown that the fundamental detection, resolution and estimation error bounds of the MIMO configuration are generally superior to any approach that only exploits receiver array geometry (with equal performance emerging as a worst case). By employing a special sequence of transmit waveforms, this virtual SIMO framework is then incorporated into a novel space-time receiver architecture which performs joint estimation of Doppler, relative path delays and direction of arrival (DOA). In this way, the effects of Doppler and path delays are not only mitigated, but used to actively enhance the capabilities of the parameter estimation system.
