Overlapped-MIMO Radar and MIMO Cellular System
2017In this chapter, we explore a collocated overlapped multiple-input multiple-output (Overlapped-MIMO) radar waveform design, which is combined with an algorithm to share spectrum through null space projection (NSP) for the coexistence of radar and communications system.

The ability of MIMO radar to measure propagation delays from each transmitter to each receiver allows the concept of the sum co-array, reviewed, to be exploited. The sum co-array allows virtual elements to be synthesized and in some cases this can lead to performance advantages. The relationship of the ES matched filter to the sum co-array is discussed

MIMO radar target measurements
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011Widely-spaced Multiple-Input Multiple-Output (MIMO) radar seeks to exploit an angular diversity of measurements in order to improve target detection performance. Such systems have been predicted to outperform equivalent phased-array configurations given a suitably low-noise environment.

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.

Abstract : The performance of a ground moving target indicator (GMTI) radar is strongly driven by the length of the radar aperture, as longer apertures enable lower minimum detectable velocity (MDV) and better target geolocation. Multiple-input multiple-output (MIMO) techniques can enable the use of long sparse array geometries while avoiding the ...

MIMO Radar Ambiguity Functions
IEEE Journal of Selected Topics in Signal Processing, 2006Multiple-input multiple-output (MIMO) radar has been shown to provide enhanced performance in theory and in practice. MIMO radars are equipped with the ability to freely choose their transmitted waveforms at each aperture. In conventional radar systems Woodward's ambiguity function is used to characterize waveform resolution performance.

MIMO radar, SIMO radar, and IFIR radar: a comparison
2009 Conference Record of the Forty-Third Asilomar Conference on Signals, Systems and Computers, 2009This paper focuses on a simple beamforming problem and compares the MIMO and SIMO radar systems for the case where the transmitter and receiver are collocated. The simplicity of the application allows one to see clearly where the advantages of MIMO radar come from, and what the tradeoffs are.

In this chapter, we review various probing waveform transmission schemes for multiple-input multiple-output (MIMO) radar with co-located antennas. An orthogonal probing waveform set is required to separate the transmitted waveforms at the receiver side to achieve a large virtual array size afforded by the MIMO radar.
