摘要
The traffic control method using radar involves emitting an electromagnetic wave at a carrier frequency (F) modulated to a much lower modulation frequency (Fm). It involves mixing a received electromagnetic wave with the emitted wave. A spectral beam is filtered corresponding to a harmonic of an order to impair the modulation frequency. A target presence signal is emitted when the filtered spectral beam has an amplitude above a set level.
