[0090] According to the information, the critical shooting conditions of a 152mm plus howitzer are:
[0091] (1) Full size charge, initial velocity 655m / s, shooting angle 45°,
[0092] (2) No. 4 charge, initial velocity 241m / s, shooting angle 20°.
[0093] A certain type of continuous wave Doppler fuze has a carrier frequency of 750MHz, and it starts to work 5 seconds before landing, and the optimal detonation distance is 2-10m. Fuze transmitting antenna gain D t =10, fuze receiver antenna gain D r =1.6, fuze transmitting antenna direction coefficient F t =0.707, fuze receiving antenna direction coefficient F r = 0.866.
[0094] A jammer presses image 3 Positional relationship, arranged at a distance of X from the drop point 0 = 200m, the jammer adopts an aiming jamming method, and the amplitude modulation frequency Ω = 1kHz.
[0095] According to the critical parameters of howitzer shooting, step (10) is performed, and the maximum falling speed of the fuze is 397.90m...
