Problems solved by technology

At present, the artillery radio frequency related to the shot-by-shot aiming is obtained through a large number of experimental digital simulations or trial and error methods, which takes a lot of time and lacks a theoretical basis
At present, there are some reports on the research on radio frequency of weapon systems, but they do not consider the indispensable constraint of shooting preparation time in the actual shooting process of aiming guns one by one, so the research results do not conform to the requirements of weapon systems. The actual situation of the shooting process

Embodiment 1

[0072] This example is applied to the demonstration and design of a shot-by-shot aiming artillery radio frequency.

[0073] (1) Let the radius of the elliptical shooting gate ρ=limil, and the two uncorrelated normal white noises pass through the transfer function as

[0074] Φ ( s ) = 1 s 2 + s + 1

[0075] The shaping filter of , taking its output uncorrelated ergodic functions x(t), y(t) as the analog quantities of the shooting element errors in two directions (set the unit as mil), obviously has

Embodiment 2

[0091] This example applies to the inspection of weapon systems.

[0092] Currently, there are three sets of error data of actual artillery shooting with a sampling period of 40 ms, which are respectively integrated into azimuth x(k) and elevation angle y(k) curves with 2998 sampling points and a duration of 119.88 seconds, as shown in image 3 shown.

[0093] If the shooting preparation time T is taken δ =1.9s, elliptical shooting gate: short axis a=lmil, long axis b=1.768mil, now analyze its average radio frequency γ j . count the corresponding

Abstract

The invention discloses a calculating method for percussion frequency of one-by-one aiming artillery. The method includes: by applying the random passage theory and taking into consideration of existence of firing preparation time of the one-by-one aiming artillery during firing, obtaining a random passage period probability density function of firing data errors according to random passage frequency of the firing data errors of the artillery passing through a firing gate; and calculating average percussion period and average firing frequency of the artillery according to a density function of random percussion period of the artillery. An effective calculating method is provided for design and detection of firing frequency of the one-by-one aiming artillery.

Description

technical field [0001] The invention belongs to the field of weapon system effectiveness analysis, and is used for calculating the combat technique index of the shooting frequency of a shot-by-shot aiming artillery when designing and verifying the weapon system. Background technique [0002] The shooting method of traditional shot-by-shot aiming artillery, such as ground guns and assault guns, is as follows: after each firing is completed, the shooting impact load causes the barrel of the artillery to vibrate randomly, and the shooting elements of the artillery at high and low angles and azimuth angles The size and direction of the error are random, and it is necessary to wait until the vibration transition process is basically over, and the shooting preparation (recoil, recoil, loading, aiming) is completed before the artillery can fire the next time. For modern shot-by-shot automatic artillery, especially the automatic artillery that fires on the move, whether it is vehicl...
