Abstract :
This paper presents a theoretical investigation of the antijamming capability of the injection-locked microwave limiter-discriminator against cochannel monotone interference. The signal-to-interference-induced noise power ratio at the discriminator output has been calculated as a function of the input carrier-to-interference power ratio. The SNR output of the proposed limiter-discriminator is found to be much higher than that obtained in the case of a passive hybrid-tee microwave discriminator preceded by an amplitude limiter
