Abstract: A method and system is provided for real-time detection of important multiple pulsed or CW signals of varying amplitude and frequency, from a group of simultaneously intercepted wideband intermediate frequency (IF) channels. The method is implemented in a channelized receiver system with a parameter encoder which filters the IF signals in a time-shared mode by dividing the IF channel bandwidth into progressively decreasing sub-band levels, multiplexing the IF signals from each sub-band and analyzing the time multiplexed IF signals to obtain the IF signal parameters. The system is flexible with programmable parameters and has the ability to eliminate most of the spurious signals with high probability of interception of the real signals. Conventional pulse descriptor words, band limited pre-detection samples and time-frequency pulse images are output for subsequent analysis or tactical application.
