Laser guidance missile changing laser energy simulation method for unmanned aerial vehicle and system

Abstract

The invention discloses a laser guidance missile changing laser energy simulation method for unmanned aerial vehicles and system. The method comprises: (1) calculating laser energy at different distances by using a laser guidance head detector according to an aerial hanging flight test or a ground running test or a target flight test of a laser guidance missile laser guidance head of the unmannedaerial vehicle to draw a laser energy-distance curve; (2) determining the laser energy value received by the laser guidance head detector at the current moment according to the target relative position relation resolved in real time in a simulation process in combination with the laser energy-distance curve; and (3) sending a laser to the laser guidance head detector in a laser direct mode at thesimulation process, so that the laser energy value received by the laser guidance head detector at the current moment is consistent with the laser energy value determined at the corresponding moment in (2). According to the laser guidance missile changing laser energy simulation method for the unmanned aerial vehicles and the system, the flight process of the missile in the air is simulated more completely, thereby improving the efficiency and the accuracy of a semi-physical simulation system.

Description

technical field

[0001] The invention relates to a simulation method for variable laser energy used in unmanned aerial vehicle laser guided missiles. The laser target signal simulator is designed so that the energy can gradually increase according to the distance from the target. The flight process improves the efficiency and accuracy of the semi-physical simulation system. Background technique

[0002] At present, laser semi-active guidance is widely used for missiles mounted on integrated UAVs. Due to the good monochromaticity of laser and small beam spread angle, it is difficult for the enemy to effectively interfere with the guidance system, and the irradiation accuracy is generally within 1 meter. , so laser-guided weapons attacking fixed or moving targets have advantages that other guidance methods cannot match.

[0003] There are two ways to launch laser-guided missiles from the surveillance-strike integrated UAV:

[0004] The first working mode is the target locking...

Examples

Embodiment 1

[0055] When the UAV launches an airborne laser-guided missile, it first searches, finds and locks the target through the airborne photoelectric reconnaissance load, and then uses the airborne laser irradiator to emit a laser beam to the target, and the laser seeker of the UAV airborne missile passes through the Receive the laser echo diffusely reflected by the target, identify and solve it and lock until it hits the target. Due to the good monochromaticity of the laser and the small beam divergence, it is difficult for the enemy to effectively interfere with the guidance system, and the irradiation accuracy is generally within 1 meter. Therefore, laser-guided weapons attacking fixed or moving targets have advantages that other guidance methods cannot match.

[0056] In the early stage of missile design, in order to speed up the development progress, reduce the development cost, and reduce the number of field target test flights, semi-physical simulation systems are often used t...

Embodiment 2

[0075] The specific embodiment 2 of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] like figure 1 As shown, a variable laser energy simulation method for UAV laser guided missiles is characterized in that:

[0077] In the missile semi-physical simulation system, the variable energy laser target signal simulator U11 is used to simulate the change of the target laser signal received by the laser seeker U12 during the flight of the missile, and the missile flight simulation is carried out;

[0078] The semi-physical simulation system includes a simulation control telemetry system U3, a simulation computer U2, and a five-axis turntable U1;

[0079] The five-axis turntable U1 is divided into three inner axes and two outer axes. The inner three axes are used to simulate the flight attitude of the missile to realize the roll, yaw and pitch motion of the missile; the outer two axes are used to simulate the target...
