Comparison of The K-Pulse and E-Pulse Techniques for Aspect Independent Radar Target Identification

摘要

It has been demonstrated that under laboratory conditions the natural resonant frequencies of a metallic scattering body may be used as the basis for target identification techniques. This thesis continues research into two such techniques: the difference equation based K-Pulse and the integral equation based E-Pulse. A double Gaussian smoothing function has been used in conjunction with the K-Pulse and basis functions of varying widths have been used in formulating the E-Pulse to provide enhanced performance in low signal to noise level environments. Digitally noise polluted synthetic scattered signals are used to analyze the effectiveness of the two techniques in distinguishing high, medium and low-Q targets. Both methods are shown to merit further study as potential candidates for implementation as Resonance Annihilation Filters for real-time radar target identification in a real-world environment.
