Radar apparatus for combining and displaying data from a plurality of radar antennas

摘要

A radar apparatus is provided which correctly combines and displays detected data obtained from a plurality of radar antennas. Detected data obtained from a radar antenna 11 is subjected to a correlation process in a correlator 91A. Detected data obtained from a radar antenna 21 is subjected to a correlation process in a correlator 91B. A mask image which designates the same address as that of the correlated data from the radar antenna 21 is set by a mask area generator 32 and is written into a mask image memory 62. For the correlated data from the correlators 91A and 91B, addresses corresponding to installed positions of the radar antennas 11 and 21 are set. For a process image memory 902B of the correlator 91B and the mask image memory 62, a common address is set. Correlated data input in accordance with mask data is stored in a display image memory 61 in accordance with an address set in a display screen and is also output to a display device 10.
