发明名称 CORRECTION SYSTEM FOR ADAPTIVE DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a correction system for an adaptive antenna device capable of correcting the difference of amplitudes/phases between branches. SOLUTION: Each of signal transmitters 1-8 for correction has a signal transmitting part for transmitting a signal sequence, which is not correlated with the other transmitter, a receiver 1-B of an adaptive antenna device 1-A has a reference signal generator 1-9 for generating the reference signal of the same signal sequence as a transmitting signal at timing deviated just for the arrival time of a direct wave, signal detecting part 10 for correction for detecting a received signal having a high correlation with the reference signal, correction table generation part 1-11 for generating the correction table of the received signal, directivity control part 1-7 for finding an amplitude and a phase to be weighed, and directivity forming part 1-6 for weighing and synthesizing the amplitude and the phase with the received signal, and each of signal transmitters for correction and receivers has a time synchronizing part 1-13.
