ABSTRACT:
Disclosed is a signal detector including a bank of digitally synthesized rowband filters all having the same shape of frequency response and differing only in center frequency and which are implemented by time domain data processing. The invention is comprised of: a signal conditioner, an envelope weighting computer, a Fourier transform processor and a post-detection processor. Resulting therefrom is a bank of 16 contiguous narrowband filters having high selectivity along with a corresponding bank of envelope detectors of wide dynamic range which incorporates center frequency acquisition and tracking. Following detection, a matched filter capability is included to provide correlation and data regeneration so that coded FSK data burst signals can be extracted in real time from noise, interference, and jamming signals which would otherwise affect signal detection.
