Key Technology for Marine Automatic Antenna Matching Adjuster Design

According to the function requirements of marine automatic antenna matching adjuster, a design scheme of its China made hardware is set forth, in which some methods such as measuring count values of carrier wave half period, summing four power average values of calculating error, fast matching arithmetic, reasonably setting up separate frequency coefficients and storage capability etc. are adopted. And also, some key technologies such as the accuracy improvement of measuring frequency, the automatic adjustment Algorithm of II model capacitance inductance matching net, the speed increase of automatic adjustment and the net parameter storage ete have been solved. These technologies have been already used in the automatic antenna matching adjuster products made in China, of which the performance indexes e.g. real matching effectiveness, adjustment time etc. is equivalent to that of imported products.
