Simulation calculation of air-to-air missile attack area based on improved secant method

In response to the demand for real-time simulation of air-to-air missile attack by rapid change of air combat situation, the computational strategy of attack zone simulation using the cut-line method is proposed. Firstly, the conditions for the missile to eventually destroy the target are determined, secondly, the far boundary of the attack zone is calculated by the cut-line method, and finally the far boundary of the attack zone that satisfies the destruction conditions is obtained For the successive calculation of the attack zone in the course of the flight of the carrier aircraft, the warm-up is proposed based on the simulation of the attack zone by the cut-line method, and the results of the attack zone calculation of the first two times are used as the initial value of the cut-line method. This will further accelerate the convergence speed of the cut-line method. Compared with the conventional attack zone simulation method, the warm start calculation of the attack zone boundary is characterized by fast calculation and high accuracy.
