Abstract

This paper describes a new signal processing technique to improve the detection accuracy of underground radar system (pulse radar). A remarkable characteristic of this new signal processing is the process of extracting a target echo using frequency domain information. The observation signal is divided into several segments, which are trans formed into a corresponding frequency region for evaluation of the spectrum distribution and computation of the frequency parameter values for that distribution. The target signal can be extracted by comparing the target signal parameter values with the reference frequency parameter values of the target signals. This technique clearly discriminates the targets from among other objects.
