PURPOSE:To realize an apparatus which is free from the possibility of being destructed by a missile of which the track deviates, and which has a wide measuring scope and is economical and convenient for handling. CONSTITUTION:First and second ballistic wave detecting sensors SA and SB are disposed at a prescribed interval L on a straight line 10 being apart from and parallel to a standard track 13 of a missile to be measured. Detection outputs thereof are inputted to a time interval measuring unit E through first and second wave-shaping units DA and DB respectively and a time interval T between them is measured. Measured data thus obtained are inputted to an arithmetic unit F, the speed (v)=L/T of the missile to be measured is computed by using the interval L set beforehand, and the data obtained thereby are displayed by a display unit G. Besides, the data are outputted outside as occasion demands. |
