Title: Apparatus for measuring speed of projectile
Inventor: SUGANO MASAMI
IPC: F41G3/00
Filed: 1987-02-23
Abstract: PURPOSE:To measure the flying speed of a projectile with high accuracy without receiving restriction of the Radio Law, by constituting the title apparatus of a laser oscillator, a beam expander, a semipermeable mirror, a total reflection mirror, a beam detector, a frequency memory device and a frequency tracking device. CONSTITUTION:A beam expander 9 magnifies the laser beam emitted from a laser oscillator 8 in required magnifying power and a semipermeable mirror 10 splits said laser beam into reference beam R and sample beam S. Total reflection mirrors 11a, 11b irradiate a projectile 2 with both beams R, S so as to cross said beams at a required angle. The total reflection mirror 11b is allowed to coincide with a reference axis at the center thereof and receives the scattering beams generated when both beams R, S are reflected from the projectile 2 at a required effective caliber to send the same to beam detector 4. Subsequently, the output signal of the detector 14 is amplified by an amplifier 15 and a frequency memory device 16 instantaneously stores the frequency thereof. A frequency tracking device 17 calculates the flying speed of the projectile 2 on the basis of the signal from the memory device 16. A voltage control oscillator 18 attains to shorten a searching time by manually setting the Doppler frequency corresponding to the preliminarily estimated flying speed of the projectile 2.
