<p>PROBLEM TO BE SOLVED: To provide an interference suppressing technique in the case where a conventional technique is unadoptable, as an interference suppressing technique between a plurality of FM pulse radar devices. SOLUTION: This FM pulse radar device group is provided with a pulse width regulator 20 capable of variably setting pulse width, and a waveform memory 21 outputting FM pulses without changing the lower limit frequency, upper limit frequency and frequency change pattern of transmit FM pulses even when the pulse width changes. The readout signal is converted into an analog signal by a digital-to-analog converter 22 and sent to a transmitter 11 after eliminating unwanted signals across the pulse width by a waveform shaper 7, and the compression characteristic of a compressor 25 on the receiving side is conformed to the compression of an FM pulse signal of pulse width set by the pulse width regulator 20, to suppress the input signals of the other pulse width.</p> |
