Title: Plotting radar device and plotted position calculating method
Inventor: YAMAKAWA KATSUYA
IPC: F41J2/00
Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a plotting radar device and a plotted position calculating method actualizing the abridgement of the time required to calculate a plotted position. SOLUTION: In this plotting radar device, each time a position on a trajectory is calculated one by one by a sector method, the altitude of a target is compared with the altitude of the ground surface at that position by a comparison part 4 to acquire the height of the target from the ground surface. As the result of this comparison, when the altitude of the target from the ground surface is higher than a predetermined reference value, the calculation of trajectory positions by the sector method is continued. On that occasion, a sector time T is varied by a sector time setting part 5 according to the altitude of the target from the ground surface and the trajectory calculation is carried out one by one under the variedly-set sector time T.  Further, the sector time T is lengthened when the target is at a high position from the ground surface, and the sector time T is shortened as the target comes closer to the ground surface.
