Experimental Evaluation of Radar Waveforms for Spectral Coexistence using the PARSAX radar

This paper investigates the possibility of transmitting waveforms designed to enable spectral coexistence between radar and other Radio Frequency (RF) wireless systems via a Software Defined Radar (SDR). The design technique tested in this study nominally enables the placement of notches in the spectrum of the synthesized probing radar signal...

Experimental study on multi-channel waveform agile beamforming and testbed calibration

In this paper, a novel multi-channel waveform agile radar testbed - ASTAP (Advanced Space-Time Adaptive Processing) with eight transmit channels and a single receive channel to form a co-located Multiple-Input Single-Output (MISO) radar is presented. Based on current configuration, the ASTAP radar system possesses agility for synthesizing and...

Accurate Target Localization for Automotive Radar

Automotive radars suffer from low angular estimation accuracy due to the limited number of antennas and insufficient onboard processing power. This paper addresses the single target tracking problem in automotive radar by using recently proposed MIMO-monopulse approach which blends the monopulse approach with the collocated MIMO radar. We...

Improved Microwave Imaging by Wavenumber Domain Multiband Data Fusion

A matrix-pencil based wavenumber-domain multiband fusion approach is proposed for improved microwave imaging. The suggested fusion approach is based on the fact from the Born approximation that the wavenumber-domain signal in a given scattering direction can be represented as a sum of the same number of contributions over the whole bandwidth....
