The structure of the missile seeker

The missile seeker is usually installed at the front end of a missile or rocket as part of the flight control system, playing a role in guiding the missile or rocket's flight. Its structure is complex, including various sensors, control circuits, communication devices, etc,

1. Sensor

The main task is to detect targets and provide guidance information for missiles or rockets, so it mainly includes various sensors.

Optical sensor: Optical sensor is one of the main sensors of the seeker, usually including infrared detector (IR) and television detector (TV). Infrared detectors identify the type and location of targets by detecting the infrared signals emitted by them. Television detectors provide guidance information for missiles or rockets by capturing target images and transmitting real-time image information.

Radar sensor: A radar sensor is another main sensor that detects radar signals emitted by targets, identifies target positions and velocities, and provides guidance information for missiles or rockets.

Inertial measurement unit (IMU): inertial measurement unit is one of the important components. It provides missile or rocket attitude information and guidance information by measuring the acceleration and angular velocity of the missile or rocket.

2. Control circuit

The control circuit of the seeker is responsible for processing data collected by sensors, calculating the flight status of the missile or rocket, and providing guidance information for the missile or rocket. The control circuit is usually composed of digital signal processors (DSP), microprocessors, analog circuits, etc., which can process the information collected by sensors in real-time and provide accurate guidance information.

3. Communication equipment

It is usually necessary to communicate with the flight control system of a missile or rocket to transmit guidance information. Communication equipment usually includes radio frequency circuits, data transmission circuits, etc., which can ensure the timely transmission of guidance information and ensure the flight accuracy of missiles or rockets.

4. Housing

The outer shell is made of high-strength materials, which can resist the strong aerodynamic forces and high inertial forces during high-speed flight. At the same time, the housing also needs to consider protecting the sensor from external interference to ensure that the sensor can accurately detect the target.
