The beampattern of MIMO (Multiple-input Multiple-output) radar is the product of transmitter and receiver beam pattern. Exploiting uniform linear array, the beampattern has no grating lode when a certain relation between the space of transmitter element and receiver element is met. Moreover, this kind of collocation takes on maximum virtual array aperture. Exploiting non-uniform linear array, the...
MIMO radar systems can increase the radar resolution, the number of targets that can be identified, and the flexibility in beampattern design in comparison with standard phased array radars. To date, most of the work on MIMO radar has been performed assuming the signals are narrowband. However, wideband signals can improve radar resolution, among other benefits, and are sometimes unavoidable when...
We analyse an iterative adaptive multiple-input-multiple-output (MIMO) radar receiver in the situation where a K L-variate adaptive transmit-receive beamformer is structured as the Kronecker product of a K-variate (transmit) and an L-variate (receive) beamformer. We present results for the special case of two clutter propagation modes separated in elevation angle, where the direction-of-departure...
A demonstration of multiple-input multiple-output over-the-horizon radar is presented. Transmitter signal beam- forming on a multi-element array has been created, not conventionally before transmission at the transmitter facility, but, after radar signal transmission, skywave propagation, target scattering, return signal propagation, and reception using an over-the-horizon radar receiver. Transmitter...
