The capability of ultra-wideband (UWB) radar or sonar systems for extracting signature information useful for target-recognition purposes is well known. The signal processing techniques to be used in the microwave or ultrasonic cases are quite similar. The frequency content of the interrogating signals is usually designed to match the size and type of target and environment present. In the radar case,...
We study the advantages and performance of an impulse sonar that uses the short, energetic pulses emerging from underwater explosions as its sources. This transient analysis is carried out for various simple targets of interest, in the time-domain, in the frequency domain and in the combined time-frequency domain. The first two, more traditional, approaches are contrasted with a third and more...
