Coherent collocated MIMO radar demonstration for air defence applications

Abstract

Coherent collocated MIMO radar is an emerging technology from which is expected several benefits since digital and adaptive beamforming are available at both transmit and receive sides. A large number of papers are dealing with theoretical analysis of those benefits. Nevertheless, few experimental performance assessments of those benefits have been reported. During the last few years, ONERA has built a powerful and versatile surface radar testbed named HYCAM. Its design included a MIMO mode in order to test the different classes of waveforms in real conditions (hardware defaults, clutter characteristics) which can hardly be modeled with accuracy. After a recall of the MIMO processing principles, this paper sums up the benefits and drawbacks that are expected from this technology and the need of experimentation to verify those expectations. Then we will present ONERA's HYCAM MIMO testbed and first results of MIMO trials using this system as well. Those experimental results will be linked to a more general discussion on impacts of hardware defaults on MIMO radar waveforms performances.

Extended orthogonal matching pursuit for robust and fast target localisation in multiple‐input multiple‐output radar

“…Therefore, two targets are expected to be detected at short range (order of the hundred of metres) and angle of 0 o . Extended description of the signal generation and processing is given in [6] and [23]. Finally, we have applied the target detection methods described in this work on the experimental signals: the matched filter as standard method, the IAA as accurate (but long to compute) method, the classical OMP, and the extended OMP.…”

Challenge problems in spectrum engineering and waveform diversity

“…In [20] Baylis, et al, describe new methods for joint circuit/waveform design for use in reconfigurable radar transmitters to enhance spectral containment. Finally, Constacias, et al, [21] presents results from experimental trials of the French HYCAM radar that possesses MIMO capability.…”

An Imaging Plane Calibration Method for MIMO Radar Imaging

“…Aerial targets imaging is an important research direction in the field of radar imaging technology. Especially, it plays a crucial role in the military field, such as, aerial defense [1] and anti-missile defense [2] and so on. Multiple-input multiple-output (MIMO) radar is a new radar technique, which adopts multiple transmitters and receivers.…”
