<p>PURPOSE:To prevent degradation of picture quality and to eliminate deviation of position relationship on display between its own airplane and a target point by performing phase compensation and range walk compensation accurately even if the airplane makes turn. CONSTITUTION:Rotation conditions are detected by a turn condition detector 9. A position compensation data compensator 12 uses an error component data memory 11 to compensate the phase compensation data calculated by a phase compensation data calculator 10. A range walk compensator 8 performs range walk compensation using a compensation period data memory 13. When a target point enters a range where no processing can be made, control is made so that no processing is made by a process controller 19. When the position relationship on display between its own airplane and the target point deviates, the position relationship with the target is calculated by a target point coordinate calculator 20 and the display azimuth angle is controlled by a display controller 21.</p> |
