Multiple Input Multiple Output (MIMO) cable guided radar presents a true paradigm shift in leaky coaxial cable sensing. Recent technology advancements in Software Defined Radio (SDR) allow this covert terrain following radar to provide reliable detection and pinpoint the location of intruders as they cross the perimeter.

On Transmit Beamforming for MIMO Radar
IEEE Transactions on Aerospace and Electronic Systems, 2012Methods for transmit beamforming in multiple-input multiple-output (MIMO) radar based on the design of multiple correlated waveforms have been proposed. This paper points out that this approach couples the spatial (beamformer) and temporal (waveform) parts of the problem, significantly complicating the design.

On spatial processing in MIMO radar
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011We develop a signal model for MIMO radar which takes into account delay and Doppler mismatch due to the fact that scatterers do not generally lie in the center of delay/Doppler resolution cells, as is commonly assumed in the literature on this subject.

On Signal Models for MIMO Radar
IEEE Transactions on Aerospace and Electronic Systems, 2012A detailed model for the signal received by a multiple-input multiple-output (MIMO) radar from point scatterers is derived and compared with a simplified model frequently used in the literature. The simplified model assumes discretization of the scatterer delays and Dopplers and a particular way of handling the out-of-bin radar returns.

Unlike traditional phased-array radars that need successive scans to cover the entire field of view, MIMO radar transmits orthogonal waveforms from each antenna element simultaneously, allowing the illumination of all targets at once. Also, better detection performance and a high spatial resolution can be obtained using all the components extracted by ...

2010 IEEE Radar Conference, 2010
Two classes of MIMO radars are briefly considered. MIMO radars with colocated antennas and coded signals represent a new and prospective concept. MIMO Radars with widely separated antennas (“Statistical MIMO radars”) are a particular case of well-known Multisite (Multistatic) radar systems.

Multiple-input multiple-output (MIMO) extensions to radar systems enable a number of advantages compared to traditional approaches. These advantages include improved angle estimation and target detection. In this tutorial, an overview of MIMO radar is provided, and the concept of coherent MIMO radar is defined.
