Abstract

Bistatic sonar1 can be employed for target regions outside an ellipse surrounding the source and receiver. However, it is particularly hard to obtain useful detection inside the ellipse (i.e. directly between the source and receiver) due to the very strong “direct blast” from the source. Using traditional processing techniques, this “direct blast” overwhelms any signature from a target located inside this ellipse, and the target is masked.
