a Method and Apparatus for Automatic Jammer Frequency Control of Surgical Reactive Jammers is disclosed. The
system and method to autonomously and selectively
jams frequency-hopping signals in near real-time. The
system has the ability to automatically detect
short duration signals (such as those output from frequency hoppers), to automatically determine if detected
signal(s) should be jammed, and subsequently to automatically and extremely quickly activate the jamming
transmitter on the frequency-hopper
transmitter's frequency. Furthermore, the
system improves upon the FFT-based front-
end system by incorporating a module that automatically and iteratively comparing the digital FFT results to the analog RF
signal to arrive at a
total frequency offset between the FFT results and the
analog signal so that the transmitted jamming
signal will be more accurately applied on the desired or target frequency. Finally, the system provides a programmable
user interface so that operators can set up the system to act autonomously as intended, such that operator intervention is unnecessary when the system is placed in jamming
operation mode.
