Problems solved by technology

Since the missile adopts a short-term high-thrust launch scheme, the launch impact is relatively large. During this process, the complex optical circuit of the seeker may be affected. Once the relative positions of the components inside the optical system change slightly, it will seriously affect Tracking and locking of the seeker to the target

Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings.

[0033] This embodiment provides a predicted target position, see attached figure 1 The specific steps of this method are as follows:

[0034] In the first step, before the missile launch, the guide is locked to be tracked, and the target information is calculated in real time, the target information includes the speed information of the target and the location information of the target;

[0035] The speed information calculation method of the target is as follows: The guiding head is set for each time Δt = 100 ms to calculate the lateral speed V of the target. z = (W y1 + w y2 ) × R / 2 longitudinal speed V y = (W z1 + w z2 ) × r / 2, where W y Indicates the angular velocity of the guide header position, W y1 The angular speed at T, W y2 The angular velocity at T + Δt; W z For guide head speed, W z1 The angular speed at T, W z2 The angular velocity at the T + Δt; R is the ...

Abstract

The invention discloses a seeker control method for predicting a target position, which belongs to the technical field of seeker control methods. The method is as follows: after a missile is launched, calculate the predicted position of the target in a three-dimensional coordinate system [X T Y T Z T ]: Calculate the two frame angles when the seeker tracks and locks the predicted position of the target according to the predicted position of the target, that is, the pitch frame angle χ′ and the yaw frame angle δ′; the calculated pitch frame angle χ′ and The yaw frame angle δ' is compared with the actual pitch frame angle χ and yaw frame angle δ of the seeker during the flight of the missile to judge whether the seeker during the flight of the missile is tracking the wrong target or missing the correct target; the method According to the attitude information of the seeker itself and the position and attitude information of the missile, combined with the target information tracked and locked by the seeker before the missile launch, predict and judge the target information tracked by the seeker after the missile launch, and confirm the tracked target Is it correct to make sure the seeker captures the correct target.

Description

Technical field [0001] The present invention belongs to the introduction of the guide head control method, and in particular, the present invention relates to a guiding head control method for predicting the target position. Background technique [0002] The guidelines are the core components of precisely guided weapons. The core task is the continuous and effective lock of the target, especially for missiles that are locked before the launch, and launched missiles. Since the missile uses a short-term powerful transmit scheme, the launch impact is large. In this process, the integrated optical circuit of the guiding head may be affected. Once a small change occurs in the relative position of each component inside the optical system, it will seriously affect Tracking lock of the target to the target. If the guidelines are lost or the error, the flight task will fail. It is therefore necessary to use a guidance head control method to complete the probability of reagent to the corre...
