More Information
Summary:The invention discloses a helicopter cooperative positioning method. The method comprises the following steps: 1, carrying out discrete processing on a set positioning area; 2, deploying a helicopter,presetting measurement nodes and collecting positioning information; 3, establishing an active dictionary; 4, estimating a target position by using a compressed sensing recovery algorithm based on sparse Bayesian learning; 5, planning the flight path of the helicopter by using a simulated annealing algorithm, and re-acquiring positioning information; and 6, repeatedly executing the steps 3 to 5,and taking a final iteration result within a preset time limit as a target positioning result. In combination with other structures or methods, the problems that in the prior art, when the helicopterflies and the measurement distance is increased, the positioning performance of a compressed sensing positioning technology is sharply reduced, accurate positioning cannot be realized in practical application, and it is hard to
