<p>PURPOSE:To prevent the deterioration of the accuracy and stability of a smoothing speed caused by an angle measuring error due to a short sampling interval. CONSTITUTION:In order to adaptively perform tracking beam scanning against a target to be detected, a detecting time difference calculating section 3 calculates the time difference between the preceding updating time to the current detecting time and a kinetic mode discriminating section 4 discriminates the movement of an airplane. Then a flying direction calculating section 5 finds the flying direction of the airplane. A smoothing coefficient calculating section 6 calculates a smoothing coefficient from the position, flying direction, and kinetic mode of the airplane and detecting time difference and a smoothing processing section 2 performs a speed updating process.</p> |
