Abstract
The invention belongs to the air-to-air missile seeker technology, and relates to a strapdown stable infrared imaging marker. The strapdown stable infrared imaging marker includes a hood, a primary imaging component, a lens barrel, a rotary transformer, a housing, a quadruple mirror group, a roll drive system, a detector, a pitch drive, a body, and a secondary imaging Components, substrates. Among them, the head cover is set at the front end of the position marker, the primary imaging component is set on the lens barrel, the lens barrel is connected with the pitch drive and resolver through the shaft hole connection mode, and the pitch drive and resolver are fixed on the coaxial hole on the body inside. The secondary imaging assembly is installed on the body, the quadruple mirror group is arranged inside the rotary transformer, and its incident and outgoing light beams are both constrained on the roll axis. The missile seeker using the strapdown stabilized infrared imaging marker of the present invention has a fairing diameter of about 90mm, realizes a large tracking field of ±90°, effectively reduces the size of the projectile diameter, and improves the aerodynamic performance of the seeker.
Description
A strapdown stable infrared imaging marker and missile seeker technical field [0001] The invention belongs to infrared seeker technology, and relates to a strapdown stable infrared imaging marker. Background technique Infrared seeker position marker structure mainly is divided into three kinds, and the first kind is dynamic gyro stable structure, non-imaging type, as PL8, AIM-9 early type, etc. are characterized by mature technology and low cost, but the tracking angle is limited and the anti-interference ability is poor. the second It is a three-axis rate gyro stabilized structure, imaging type, such as snake 4, PL10, etc., which is characterized by complex structure, difficult to miniaturize, and gas Poor dynamic performance. The third is a two-axis strapdown stabilized structure, imaging type, such as AIM-9X, with simplified structure and small size. third position The structure of the target device can realize the characteristics of miniaturization of the seeker...
