Mono-bit multi-signals radar warning receiver

A radar warning receiver, comprising:

• a signal detection unit comprises
• a first limiting amplifier for converting a plurality of collected radio frequency (RF) signals to corresponding pulsed output signals that track frequency oscillations of said collected RF signals;
• a second limiting amplifier for converting said pulsed output signals to a plurality of frequency and amplitude signals;
• an adder connected between said first and second limiting amplifiers;
• a noise generator for injecting noise to one of said limiting amplifiers;
• a plurality of mono-bit resolution samplers, coupled to one of said limiting amplifiers, for sampling said frequency signals and noise;
• and
• a high-pass filter for eliminating noise in said sampled frequency signals output from said mono-bit resolution samplers;
• a signal identification unit for determining whether or not if any of said collected RF signals contains a threat signal, after the receipt of said plurality of frequency and amplitude signals;
• and
• an alarm for dispatching an alert in response to a determination that said collected RF signals contains a threat signal.
