SHORT PULSE RADAR AND CONTROL METHOD THEREOF

摘要

A pair pulse generator generates one pair of pulses including a first pulse having a predetermined width and a second pulse having a width equal to that of the first pulse and being behind from the first pulse by preset time each time a transmission designation signal is received. A burst oscillator performs an oscillation operation in a period in which one pair of pulses are input to output a signal having a predetermined carrier frequency as a first burst wave in synchronism with the first pulse and also output the signal of the predetermined carrier frequency as a second burst wave in synchronism with the second pulse, and stops the oscillation operation in a period in which one pair of pulses are not input. A transmitting unit emits the first burst wave into an exploration target space as a short pulse wave. A receiving unit receives a reflected wave and detects the second burst wave as a local signal. A control unit variably controls an interval between the first pulse and the second pulse.
