The invention belongs to the radar technical field and discloses a GASA-based MIMO radar orthogonal coded signal optimization method. The method comprises the following steps: establishing an orthogonal polyphase coded signal module of an MIMO radar; generating an initial population according to the established orthogonal polyphase coded signal model, and carrying out initialization on annealing temperature, iteration times and population generation number; carrying out optimization on the tth generation of population to generate a new population; judging whether the iteration times reach preset iteration times; if not, letting the iteration times and population generation number add 1 respectively and carrying out optimization on the new population, which serves as the tth generation of population, until the iteration times reach the preset iteration times; and if so, determining an optimal individual in the population and obtaining an orthogonal polyphase coded signal according to the optimal individual. The method can avoid trapping in local optimum and can obtain an excellent-performance global optimal solution.

A chain transmission mechanism includes a machine table, a transmission unit and a plurality of moving units. Wherein the machine table has a track, and the track defines a first constraint surface and a second constraint surface; the transmission unit has a chain wound around the track; the moving units are arranged in the track, and are controlled by the chain To drive displacement, each moving unit has a first rolling member that contacts the first constraining surface but does not contact the second constraining surface, and has a second rolling member that contacts the second constraining surface but does not contact the first constraining surface . Therefore, during the displacement process of these mobile units, the contact frictional resistance can be reduced. At the same time, the positions of the first and second rolling elements are arranged up and down, front and back, which can resist the problem of one side of the mobile unit being biased, so as to improve the operation of the mechanism. smoothness.
