Abstract
Generated by an ordinary Colpitts oscillator, chaotic waveforms with bandwidth larger than several GHz can be readily obtained. A prototype of chaotic signal radar with Colpitts oscillator is set up to experimentally investigate the performance of chaotic signal in radar system. The correlation traces between the transmitted and reference signals are presented, whose spike point reveals the experimental transmission distance. Experimental results show that the proposed chaotic radar has the advantages of high range resolution, high range rate resolution, unambiguous correlation profile, high electronic counter countermeasure (ECCM), and low probability intercept (LPI).
