Abstract
Recently, there has been considerable interest in noise radar over a wide spectrum of applications, such as through wall surveillance, detection, tracking, Doppler estimation, polarimetry, interferometry, ground-penetrating or subsurface profiling, synthetic aperture radar (SAR) imaging, inverse synthetic aperture radar (ISAR) imaging, foliage penetration imaging, etc. One of the major advantages of the noise radar is its inherent immunity from jamming, detection, and external interference. In this report, the basic theory of noise radar design is treated. The theory supports the use of noise waveforms for radar detection and imaging in such applications as covert military surveillance and reconnaissance. It is shown that by using wide-band noise waveforms, one can achieve high resolution and reduced ambiguities in range and Doppler estimations. Two coherent processing receivers, namely, the correlation receiver and the double spectral processing receiver of noise radar returns are described and their range estimation is presented. Mutual interference and low probability of interception (LPI) capabilities of noise radar are also evaluated. The simulation results show the usefulness of the noise radar technology to improve on conventional radars.
