Systems and methods for pulse descriptor word generation using blind source separation

A system for processing a plurality of time-varying signals to generate at least one pulse descriptor word (“PDW”) including at least one of frequency data and bandwidth data, said system comprising:

• a sensor configured to receive the at least one time-varying signal;
• a signal data processor communicatively coupled to said sensor and comprising:
• a plurality of blind source separation (“BSS”) modules, each BSS module of said plurality of BSS modules comprising a filtering subsystem comprising a plurality of filter modules, wherein each filter module of said plurality of filter modules has a frequency filter coefficient (“α”) and is parameterized by a center frequency (“f”);
• and
• a PDW generation module communicatively coupled to said filtering subsystem, said plurality of BSS modules configured to filter signals derived from the plurality of time-varying signals and transmit at least one blind source separated signal to said PDW generation module, said PDW generation module configured to generate, based on the at least one blind source separated signal, at least one PDW parameter vector signal containing the frequency data to facilitate updating, substantially simultaneously with generating the at least one PDW parameter vector signal, and based thereupon, at least one of a value of α and a value of f for each filter module of said plurality of filter modules;
• a computing device communicatively coupled to said signal data processor, said computing device configured to receive the at least one PDW parameter vector signal from said PDW generation module;
• and
• a vehicle in communication with said computing device, said system configured to direct movement of said vehicle based on the at least one PDW parameter vector signal.
