Abstract

A noise radar is a radar that transmits band limited electromagnetic noise. The radar system cross correlates the received signals with a delayed version of the transmitted signal. The correlation value as a function of the delay time is proportional to the impulse response of the target. The long integration times and the use of coaxial cable as a delay line makes such a radar inherently appropriate for very short range (less than 3 meters) slow moving or stationary targets. This means that such a radar is particularly suited to the land mine detection role. We will discuss the development of such a radar at the Ohio State University, and we will demonstrate the system using data for buried underground targets, including the OSU surrogate mine field. Time domain and frequency domain characteristics of the targets will be discussed with application to buried target classification.
