Embodiment Construction

[0061] The specific implementation manner of this scheme will be described in detail below in conjunction with the accompanying drawings.

[0062] 1. The overall scheme of the aircraft based on the predictive guidance law.

[0063] The schematic diagram of this scheme is as follows figure 1 As shown, it specifically includes: target designation system, quantum imaging system and guidance system. The target indication system is the ground laser irradiation system, which completes the functions of irradiating the target, modulating the target orientation and irradiating the reference detector, and the reflected radiation wave of the target is received by the object detector; the quantum imaging system completes the target imaging and obtains the function of angle information; the guidance system Implement the predictive guidance law, complete the generation of guidance instructions, and guide the aircraft to the target.

Abstract

The invention relates to the field of the guidance technology based on optical imaging, in particular to an aircraft forecast guidance scheme based on quantum imaging. At preset, two main factors restricting guidance accuracy of an aircraft are that target detection resolution ratio is not high and affected by scattering particles easily, and imaging is difficult under extremely weak light; maneuvering targets cannot be tracked and guided quickly. According to the aircraft forecast guidance scheme based on quantum imaging, correlated imaging is performed by recording distribution strength of a radiation field and space fluctuation of a phase, and therefore, imaging resolution ratio is increased. However, the updating rate of measured data obtained from images is not high, so that a forecast guidance rule is adopted to overcome the shortcoming that guidance accuracy of the aircraft decreases due to low data updating rate of quantum imaging. By means of the aircraft forecast guidance scheme based on quantum imaging, quantum imaging can break up limitation of a diffraction limit, the resolution ratio can reach micron dimension, and guidance on the maneuvering targets can be improved by combining the forecast guidance rule. Therefore, the aircraft forecast guidance scheme based on quantum imaging is high in accuracy, strong in antijamming capability and suitable for guiding the aircraft to track the maneuvering targets.

Description

technical field [0001] An aircraft predictive guidance scheme based on quantum imaging relates to the technical fields of optical imaging and aircraft guidance. Background technique [0002] At present, the imaging guidance technologies mainly used and vigorously developed in the field of aircraft terminal guidance are infrared imaging guidance and laser imaging guidance. Infrared imaging is a real-time scanning infrared imaging technology that detects radiation distribution images caused by small errors or radiation frequency differences between the target and the background. With the rapid development of infrared detection technology, infrared imaging guidance is called the trend of development, but at the same time, the interference environment it faces is also mature. One is natural interference, strong sunlight radiation interferes with the infrared system, causing the aircraft to lose its target; the other is man-made interference, such as aerosol, stealth technology,...
