摘要
针对目前多弹协同研究中长距离、宽速域、大空域协同弹道规划研究匮乏这一问题,同时考虑通过弹道设计降低飞行过程中雷达探测概率的实际需求,提出了一种面向突防的多导弹攻击时间/攻击角度协同的弹道规划方法。根据雷达方程,建立了威胁量化模型;针对多导弹攻击时间/攻击角度协同作战需求,给出了实现攻击时间/攻击角度协同的方法;设计了协同弹道规划求解框架,将上述协同攻击问题转化为非线性规划问题,基于hp-自适应Radau伪谱法进行求解得到了满足攻击时间/攻击角度协同的弹道,并对两种典型案例进行了仿真验证。同地先后发射和不同地同时发射情况下,均得到了满足攻击时间/攻击角度协同的弹道。仿真结果表明,该方法能够满足雷达探测威胁最小条件下,多导弹以协同攻击时间/攻击角度对目标实施打击。
For the research of the cooperative trajectory planning under the conditions of long-distance, wide-speed range and wide-area, a cooperative trajectory planning technology is proposed with radar detection conditions considering reducing the radar detection probability during flight through trajectory design. According to the radar equation, the threat of quantitative model is established to describe the probability of being detected by radar. To meet the requirement of cooperative impact time and impact angle, the impact time and impact angle constraints are given. After the flow chart of cooperative trajectory planning being given, the cooperative combat problem is then transformed into nonlinear programming problem, and it is solved based on hp-adaptive Radau pseudospectral, which is widely used in trajectory optimization field. Two cases, i.e. launch in the same place but different time and launch in the same time but different places, are simulated and verified. The cooperative trajectories meeting the requirement of cooperative impact time and impact angle can be achieved under the two cases. Simulation results demonstrate that the proposed method can fulfill the requirement that multiple missiles strike the target with the cooperative attack time and cooperative attack angle under the minimum threat of radar detection.
