摘要： A target signal analyzer having at least one receiving antenna configured to receive the target signal, and a parallel array of oscillator rings. Each oscillator ring is operatively coupled to receive the target signal from the receiving antenna. Each oscillator ring has an odd number of at least three bistable, nonlinear oscillators circularly coupled to each other such that only one-way signal flow is allowed between the oscillators in each oscillator ring. Each of the oscillator rings is configured to oscillate and thereby produce a response signal only when the target signal frequency is within a designated frequency band. For every designated frequency band in a spectrum of interest, at least one of the oscillator rings is configured to produce a response signal.
