Adaptive array antenna controller |
摘要 |
An adaptive array antenna controller is disclosed that adaptively controls weighting coefficients of multiple antenna elements of an array antenna based on a digital signal outputted from an analog-to-digital converter receiving a weighted analog signal received from the array antenna. The controller includes an impulse response measuring device for obtaining impulse responses, based on correlation calculation of the digital signal and a known signal having a predetermined pattern; an impulse response generator for extracting path components existing within a predetermined time duration from among plural path components included in the impulse responses and generating desired impulse responses; a reference signal generator for forming a reference signal having a desired pattern, based on convolution calculation of the desired impulse responses and the known signal; and an adaptive controller for adjusting the weighting coefficients, based on the digital signal and the reference signal.
