Analysis of Shipborne Helicopter’s Guidance Error in Anti-Ship Missile Over-the-horizon Attack

The over-the-horizon(oth) attack of anti-ship missile guided by helicopter is a common style in the attack of surface ship's missile. This paper does a research on the helicopter guiding error, and a proper method based on error transfer principle is proposed. Taking the unilateralism relative location method for example, the paper particularly analyzes the location error made by shipborne helicopter during the anti-ship missile over-horizon attack, and gives out formula for the error. The simulation is also used to validate the formula.
