Abstract: Aiming at the multi-constraint problem faced by hypersonic glide vehicles during reentry, a maneuver guidance strategy for route planning based on multi-tentacle detection is proposed. The maneuver guidance strategy calculates the speed-remaining ground distance-heading angle constraint through the maximum turning trajectory of the aircraft, sends out a plurality of rough prediction tentacle in a segmented fixed-point mode, and calculates the priority by referring to information fed back by the tail end of the antennae to determine a temporary road navigation point; At the same time, in the maneuver guidance mode, it sends out the fine probe tentacle, calculates the priority of tentacle end information, and obtains the control command through the sideslip angle delay filter to maneuver the aircraft. The maneuver guidance strategy for route planning based on multi-tentacle detection reduces the calculation time in the three-tentacle maneuver guidance method. At the same time, the simulation results under four typical nofly zones show that the strategy can effectively and stably solve the multi-constraint problem in the maneuvering guidance process.
