<p>PURPOSE:To measure the speed of a target with a simple construction by detecting angles at which the airframe axis of a flying object forms with a visual line while measuring the speed of a flying object and the relative speed formed by a target such as an aircraft, and the flying object. CONSTITUTION:The speed of a flying object 1 is measured by the use of an accelerometer 7, an integrator 8 and the like for detecting the acceleration of an airframe axis direction. Angles at which the airframe axis direction of a flying object forms with a visual line is measured by the use of a potentiometer 6 and the like for detecting the oscillating angles of an antenna 6. Further, the relative speed of the flying object 1 and a target is measured by the use of a Doppler processing device of receiving waves or a digital filter and the like having a function in which relative distance is differentiated equivalently. In order that the flying object 1 is steered by proportional navigation, guiding signals 11 obtained by a signal processing part 4 is needed. Therefore, the speed of a target is obtained by the above value with a simple constitution.</p> |
