Detection of Moving Targets With Continuous-Wave Noise Radar: Theory and Measurements

Abstract

This paper investigates a radar using a narrowband continuous noise waveform as an illuminating signal for the detection of moving targets. First, the theory of noise radar is presented, including the properties of the noise waveform and signal model. Next, the signal processing for noise radar is described, consisting of adaptive filtering for clutter removal, calculation of the crossambiguity function, and detection. The presented concept is validated with real-life experiments, during which cars at ranges of hundred of meters and aircraft at ranges of a few kilometers were detected.
