<p>PURPOSE:To display a target, the direction of which is identified, without carrying out mechanical matching by correcting the difference in a mechanical origin between each beam axis and antenna rotational axis, and an angular signal stored in a memory device, through computer. CONSTITUTION:Radar video signals 20-21 are input in video processors 5-6, and the angle when the video signals are input is detected by a reference angular signal 28, while angular signals 22-23 are temporarily stored in memory devices 7-8. A first memory data 26 and a second memory data 27 are constantly read from the devices 7-8 by a computer 9, while a directivity data 34 (the data indicating the difference in the mechanical origin of input antenna rotational axis) input from an input device 11 is added, and corrected data 29-30 are output to video generators 12-13, and correction video signals 31-32 are output to a video synthesizing device 14. A synthetic video signal 33 thus added and synthesized is output to a radar display device 15 by the device 14, and a radar video is displayed in the whole circumference.</p> |
