Title: Control device of central position of ppi image in radar apparatus
Inventor: KANAZAWA YUICHI
IPC: G01S7/298
Filed: 1994-09-20
Abstract: PURPOSE: To obtain a control device by which the positional relationship between a target and its peripheral target can be grasped instantaneously irrespective of the relative movement of the target with reference to a radar apparatus by controlling the central position of a PPI image in such a way that the image of the target is displayed in a fixed display position. CONSTITUTION: A display position setting circuit 10 for object to be captured sets the fixed display position of a target on a PPI image in a PPI image central position-control value computation circuit 9. The circuit 9 operates the position of its own ship due to the relative movement of the target on the basis of the fixed display position, the information on the main direction of the own ship (to be input from a direction compass), the direction of a target to be captured and on the information on a distance (to be input form a target capturing and tracking apparatus). On the basis of the position of its own ship as operated result, a PPI-image-center control value is computed in such a way that the position of the target is always fixed on a radar image, and the control value is sent to a PPI-central position control circuit 4.  As a result, even when the target is moved relatively with reference to a radar apparatus, the image of the target can be fixed on a screen for a display device 7, and the positional relationship between the target and its peripheral target can be grasped instantaneously.
