摘要： A transmitting unit emits a short pulse wave which satisfies a predetermined spectrum mask from an antenna into space. A receiving unit receives a reflected wave produced by an object existing in space of the short pulse wave emitted by the transmitting unit. A signal processing unit analyzes the object based on an output signal from the receiving unit. The transmitting unit has a pulse generator which outputs pulse signals each having a predetermined width at a predetermined frequency, and a burst oscillator which receives the pulse signal output from the pulse generator and performs an oscillation operation for time corresponding to the width of the pulse signal to output the short pulse signal. A width and a cycle of the pulse signal and an oscillation frequency of the burst oscillator are set such that almost an entire main lobe of a spectrum of the short pulse wave falls within a range of 24.0 to 29.0 GHz in the predetermined spectrum mask, and that a radiation power density to an RR radiowave emission prohibited band held by the predetermined spectrum mask is lower than a peak radiation power density of the main lobe by not less than 20 dB.

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.

摘要： A radar oscillator has an oscillation unit and first and second switch circuits. The first switch circuit turns off an electric power supply to an amplifier in a non-input period of a pulse signal to set the oscillation unit in a non-oscillation state and turns on the electric power supply to the amplifier in an input period of the pulse signal to set the oscillation unit in an oscillation state. The second switch circuit turns on an electric power supply to an LC resonator in a period immediately before the pulse signal is input in a period in which the pulse signal is not input to supply a current to the LC resonator and turns off the electric power supply to the LC resonator at a timing at which the pulse signal is input, so that activation of an oscillation operation of the oscillation unit is accelerated.
