Problems solved by technology

[0006] In the design of the laser beam steering guidance system, the zoom characteristics of the guidance instrument mainly depend on the change of the missile flight distance with time, and the design methods and principles are relatively mature; relatively speaking, the determination of the initial focus parameters of the laser guidance information field, No mature design methods and principles have been proposed yet

Embodiment Construction

[0036] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0037] This embodiment is the design of the initial focus parameters for a certain laser-beam driving gun-launched missile. The initial velocity of the beam-driving gun-launched missile is 250m / s, and the diameter of the guiding spot is D during the continuous zooming process of the guidance instrument. 1 =6m, laser link transfer coefficient K 1 = 1, the minimum missile range requirement is 200m. Since the flight time of the lead-in period is very short, it is assumed that the speed of the missile remains constant during the lead-in process. This assumption is not necessary for the methods described here, but may simplify the description and discussion of the methods.

[0038] The specific process of using the present invention to determine the initial focus parameters of the laser beam steering guidance information field is:

Abstract

The invention relates to a method for determining laser beam rider guidance information field initial fixed focus parameters. The method comprises the following steps of: (1) determining an entire missile guidance control system chart; (2) determining a mathematical model of each pane of the control system chart; (3) stringing the mathematical model of a lead compensation network to the control system chart; (4) designing a lead compensation network according to the requirements of the system on convergence rate of an introduction section trajectory; and (5) designing laser link transfer coefficients so that a step response curve of the laser link transfer coefficients is closest to the step response curve of the lead compensation network. The design results of the laser link transfer coefficients obtained from the step (5) are the laser beam rider guidance information field initial fixed focus parameters determined by the invention. The method provided by the invention can be used for fast and accurately designing the laser beam rider guidance information field initial fixed focus parameters and meets the requirements of the system on convergence rate of an introduction section trajectory.

Description

technical field [0001] The invention relates to a design method of an initial focus parameter of a laser beam steering guidance information field, belongs to the field of laser beam steering guidance, and is especially suitable for the design of the initial focus law of laser beam steering guided gun-launched missiles. Background technique [0002] Laser beam steering system is an important part of modern precision guidance technology. Due to the advantages of high guidance precision, strong anti-active interference ability, simple structure of the bomb-on device, and low cost, the laser beam-driving guidance system has been adopted by many anti-tank missiles and anti-aircraft missiles at home and abroad, such as the European "medium-range "Tigget" anti-tank missile, Russia's 9M119 gun-launched missile, Sweden's RBS70 anti-aircraft missile, etc. [0003] When laser beam steering guidance is used, before or at the moment of launch of the missile, the guidance instrument firs...
