| description | The invention discloses a trajectory design method for coupling RCS characteristics of an aircraft. The method comprises the following steps: establishing an RCS characteristic model of the aircraft through Gaussian filtering and polynomial fitting methods; comprehensively considering the influence of the maximum detection distance of the radar, the RCS of the aircraft and the distance between theaircraft and the radar, and establishing a radar detection probability model; comprehensively considering an aircraft dynamics model, an aircraft RCS model and a radar detection probability model, and establishing a trajectory optimization solving framework; and converting a trajectory optimization problem into a nonlinear programming problem based on an hp-adaptive Radau pseudo-spectral method,and performing solving in combination with a step-by-step constraint method to finally obtain a flight trajectory meeting a multi-constraint condition. According to the trajectory design method for coupling the RCS characteris |
