Subspace-Based Detection and Localization in Distributed MIMO Radars

n this paper, we consider a distributed multiple-input multiple-output (MIMO) radar which radiates waveforms with non-ideal cross- and auto-correlation functions and derive a novel subspace-based procedure to detect and localize multiple prospective targets. The proposed solution solves a sequence of composite binary hypothesis testing problems by resorting to the generalized information criterion (GIC); in particular, at each step, it aims to detect and localize one additional target, upon r...

Waveform and Filter Design in MIMO OFDM Dual-Function Radar-Communication

We consider the design of the space-time waveforms and receive filters in a multiple-input multiple-output (MIMO) dual-function radar-communication (DFRC) system employing an orthogonal frequency division multiplexing (OFDM) and a differential phase shift keying modulation (DPSK). We propose to optimize the pth power mean of the radar signal-to-interference-plus-noise ratios on each subcarrier, with p≤1 , under constraints on the transmit power, the beampattern level towards specific directio...

Exploiting Reconfigurable Intelligent Surfaces in MIMO Radar Detection

This paper considers the problem of target detection in a multiple-input multiple-output (MIMO) radar aided by two reconfigurable intelligent surfaces (RISs), one close to the transmitter and one close to the receiver. A novel signal model is first introduced, subsuming both mono- and bi-static configurations. Upon resorting to a generalized likelihood ratio test (GLRT), the RISs are then designed to maximize the probability of detection for a fixed probability of false alarm. Finally, we ass...
