摘要： A transmitter emits into an intended search space a radar wave having a predetermined frequency pulse-modulated by a trigger pulse of a predetermined width. A receiver receives a reflected wave of the radar wave and outputs a receive signal. A local pulse generator outputs a local pulse signal having the predetermined frequency pulse-modulated by the trigger pulse delayed by the delay unit. A correlation value detector detects a strength correlation value between the receive signal and the local pulse signal. A delay time changing unit changes the delay time sequentially within a range of a predetermined period representing a generation period of the trigger pulse. A correlation value storage unit stores the strength correlation value detected for each delay time changed. A frequency distribution generator generates a frequency distribution of a stored correlation value against the delay time. A search control unit executes an analyzation for the intended search space based on a generated frequency distribution.

摘要： An amplitude data generator receives L-bit data, and outputs amplitude data of a predetermined periodic function of a phase specified by the data. A frequency setter sets frequency data of (K+L−1) bits obtained by dividing a desired output frequency by a frequency of a predetermined clock signal. A K bit counter counts the clock signal. L-set product and sum computation circuits subject the frequency data of (K+L−1) bits into L-set K-bit data in which a start bit is shifted by one bit each other. Then, these circuits compute a logical product between the counter output of K bits from the counter and a bit unit, and obtains a total number of bits for each set when the computation result is 1. A shifting/adding circuit adds each total number data obtained by the L-set product and sum computation circuits by shifting a bit, and outputs the least significant L bits of the computation result to the amplitude data generator.

摘要： In a configuration according to a short-range radar of the present invention and a method of controlling the same, the timing at which a variable-period pulse output from a variable-period pulse generator including a direct digital synthesizer (DDS) has shifted in level first since reception of a search instruction is used as a reference timing, so that a signal that shifts in level at the reference timing or a fixed lapse of time later than the reference timing is generated and output as a transmission trigger signal, and a signal that shifts in level at a timing delayed by half a period of the variable-period pulse or its integral multiple from the timing at which the transmission trigger signal is output is generated and output as a reception trigger signal. With this, by varying beforehand frequency data of the DDS based on the relationship between the frequency data and delay time between transmission and reception stored in a memory, it is possible to vary delay time between the transmission trigger signal and the reception trigger signal. It is thus possible to arbitrarily vary the delay time between transmission and reception at a high time resolution by using a simple configuration and low power dissipation.

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.
