Abstract:
There remains a wide proliferation of second-generation frequency-modulated conical-scan seekers
in the hands of irregular forces while the understanding of what makes a jam signal effective remains unclear.
It is generally known that the jam-to-signal (J/S) ratio, the jam signal frequency, and the duty cycle are the
parameters that need consideration when developing an effective jam code, but the effect of using different
jammer waveforms is not generally known. Our study investigates the effect of using different jammer waveforms
namely: the fixed carrier, low frequency, amplitude modulation (AM), and frequency-modulation jam codes, for
jam signal analysis. Of the tested jam signals, it was found that the AM jam code is most effective in countering
the conical-scan seeker due to the amplitude variations created by the jam signal.
