<p>PURPOSE:To enlarge the coverage as a radar network among adjoining sites and optimize the coverage of each radar device by setting the repeating period of transmitted pulses corresponding to the pulses in compliance with the detection distance in the beam pointing direction. CONSTITUTION:The information about the antenna 4 directional azimuth sensed by an angle sensor 9 is given to a pulse width controller 10 to perform the control of the reply pulse width for varying the requisite processing range. The controller 10 controls the width of the transmitted pulses in response to the pointed direction and gives the pulse width information to a reference signal/ timing generator 1. The generator 1 sets the pulse repeating period in conformity to the pulse width information received and emits a timing signal according to the requisite processing range for the azimuth. Thus, the requisite processing range is varied by changing the transmitted pulse width and the repeating period with the azimuth so as to optimize the covering area of each radar device, and the total covering area of a radar network with a plurality of such radar devices arranged, is enlarged.</p> |
