AbstractPlanning Systems Inc. (PSI) proposes to develop and implement a new approach to active sonar signal processing. The proposed approach encompasses the design and evaluation of a new class of signal, Chaotic Frequency Modulation (CFM), that has properties of a nearly ideal 'thumbtack" magnitude squared wideband auto-ambiguity function and good suppression of distributed reverberation; the use of a modern cycle-octave wavelet time-frequency processing technique to coherently process the received signal across several octave bands, and the accurate simulation of the medium frequency (MF) broadband acoustic environment. The development will result in significant improvements in the detection of bottomed submarines and mines in a reverberant environment. Included in the development will be the capability to simulate the effects of the environment on this new class of signals as well as other types of broadband signals.
