Uav Guidance System Simulation And Flight Test Technology

In this paper, the simulation of the terminal guidance system and precision analysis for the anti-radar drone are researched, and the flight test of the drone and the analysis of its result are studied. Firstly, the random mathematics model of the guidance system is set up, with the random factors such as the seeker, the guidance law, the automatic pilot, the dynamics, the relative kinematics taken into account. Then, under the base of the model, according to the various condition,the model of the drone is simulated, and relative performance is analyzed. The influence of the wind and the seeker to precision guidance is emphasized. In flight test, using the method of system identification,the model of the dropped order is taken, then the performance of control syetem of the drone is evaluated. In order to analysize the precision guidance of the flight test, two method is usedizero time sample test and small sample test. According to the re-attacking property of the drone using the method of zero times sample test, the loss of the drone in flight test is decreased. After the data of hitting point is gotten in test, the Bayesian method, which is based on the data of the test and the information of the simulation before the test, is used to analysize the precision guidance.
