Abstract: 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.

Abstract: A radar device is provided that can reliably display sensed image data of an object, regardless of the state of the object (echo) within a sensed range and of the surrounding environment. A behavior data detector 11 generates current level detection data by detecting a level behavior of sensed image data X(n) handled by a W data generator 7 from sensed data x(n) that is output from a sweep memory 4. Previous behavior data constituted by level detection data of several past scans is stored in a behavior data memory 12, and the behavior detector 11 updates the previous behavior data with the current level detection data and outputs the result to the W data generator 7. Detecting characteristics of the sensed image data of corresponding pixels from the behavior data, the W data generator 7 selects filter calculation data W(n), the current sensed image data X(n) or specific filter calculation data Z(n) and outputs the selected result as written image data Y(n).
