Abstract

A method for generating pulse descriptor words (PDWs) including frequency and/or bandwidth data from time-varying signals 114/116 received by a sensor 103 includes filtering, at a plurality of blind source separation (BSS) modules 120, signals 124/126 derived from the time-varying signals 114/116, each BSS module 120 including a filtering subsystem 207 having a plurality of filter modules 207a/207b/207c. Each filter module 207a/207b/207c has a frequency filter coefficient ( ± ) and is parameterized by a center frequency ( f ). The method also includes transmitting at least one blind source separated signal 129 from the BSS modules 120 to a PDW generation module 128 communicatively coupled to the filtering subsystem 207. The method further includes generating, using the PDW generation module 128 and based on the blind source separated signal 129, at least one PDW parameter vector signal 138 containing the frequency data. The method also includes updating, upon generating and based on the PDW parameter vector signal 138, values of ± and/or f for each filter module 207a/207b/207c.
