Application of E-pulse Method for Remote Sensing Arbitrary Shaped Objects in Lossy Media

Aspect independent radar target discrimination method, using the natural frequencies of arbitrary shaped objects, is introduced. The approach is based on the extinction-pulse (E-pulse) technique and, as the numerical simulation shows, it is relatively insensitive to random noise and to estimations of modal contents. This method allows to discriminate superwide-band radar targets down to the signal-to-noise ratio approximately 5 dB. The results of experimental research of the signals scattered by the arbitrarily shaped objects in lossy media are presented.
