Operational process of Doyle air defense missile

In combat, the basic working process of Doyle missile has five stages: launch preparation, ejection from the frame, turning to the target, controlling flight and destroying the target. The target search radar indicates the target information to the guidance radar, and the guidance radar sends out the launch preparation information after stably tracking the target. With the help of the automatic launcher on the chariot, the function detection of the chariot and the missile is completed within 5-6 seconds, the vehicle-mounted power supply transmits power to the vehicle-mounted equipment, and the missile turning instruction is input to the vehicle-mounted autopilot (this instruction is automatically generated when the missile flies). According to the "launch" command, start the power supply on the missile. When the missile is vertically ejected to 15 to 20 meters by starting the catapult, the missile turns under the action of the rudder according to the autonomous turning command, and the engine has started to work slightly ahead of schedule, so that the missile can accelerate its flight immediately.

The guidance radar automatically intercepts the missile, makes it enter the automatic tracking state, and sends control instructions to the missile to guide it to reach the target. The guidance station emits detection pulses and realizes target tracking according to the transmitted signals. At the moment of aiming at the target, the guidance station sends control instructions and interrogation pulses to the missile. After the airborne transponder sends out the response signal, the guidance station forms the tracking error signal of the missile according to the response signal. According to this signal, the special computer for the chariot calculates the control command and sends it to the on-board autopilot through the command sending equipment to ensure the accurate guidance of the missile. When the missile approaches the target and reaches the effective killing distance of the warhead, the radio fuze will detonate the warhead in time to destroy the target.
