Abstract

The invention discloses a collimation control device, comprising a feedback unit, a signal transmitting and receiving unit, a collimation state monitor unit, an operation condition selection unit, a signal sampling unit, a control signal generation unit and an operation unit. The feedback unit is used for feeding back an optical signal. The signal transmitting and receiving unit is used for transmitting the optical signal and receiving a feedback signal which is corresponding to the optical signal and which is sent by the feedback unit. The collimation state monitor unit is used for monitoring dwell time of the feedback signal on the signal transmitting and receiving unit to obtain dwell time. The operation condition selection unit is used for selecting an operating mode according to the dwell time. The signal sampling unit is used for sampling the feedback signal to obtain a sample signal according to the operating mode. The control signal generation unit is used for obtaining a control signal according to the sample signal. The operation unit is used for controlling the feedback unit according to the control signal. The invention also discloses a collimation control method.

Description

technical field [0001] The invention belongs to the technical field of signal positioning, and in particular relates to a collimation control device and method. Background technique [0002] When the missile is launched, it is necessary to locate the missile in order to control the missile to strike the target. When locating the missile, it is necessary to set up photoelectric collimator and other equipment on the ground, so that the photoelectric collimator is aimed at the aiming window in the missile, and the plane rectangular prism in the aiming window will reflect back the laser emitted by the photoelectric collimator to realize collimation control . Ideally, the laser emitted by the photoelectric collimator will coincide with the laser reflected by the plane rectangular prism or have a small error, that is, meet the collimation control requirements; after a certain period of sampling calculation, according to the known position information of the photoelectric collimat...
