Digital beamformer and phased array antenna using complementary fuzzy adaptive signal processing algorithm

摘要

The present invention provides an apparatus and a method for receiving an initial state by first providing a relative determination criterion for the amplitude and phase of received signals in a digital manner, adjusting an evaluation time determined from an error relating to an accumulated reception state, So that the beam can always be stably directed towards the firing point by ensuring that the state always ensures optimal synthesis level and phase. According to the present invention as described above, there is provided a digital signal processing apparatus including a phase shifter and including a multi-channel receiver for receiving multiple communications and a broadcast signal, an A / D converter, a digital filter, Channel receivers from the multi-channel receiver communication and broadcast signals received from the multi-channel receiver multi-channel receiver, perform updates of the distribution and new reference values from the multi-channel receiver calculations, and perform an asynchronous evaluation A fuzzy calculator for minimizing the estimation error while adjusting the time, and a multiplier for calculating an error amount and an inverse to be compensated from the respective amplitude and phase data calculated in the multi-channel receiver fuzzy calculator, P / A for outputting the phase value and the amplitude / gain value of the channel receiver phase shifter The controller corrects the relative phase difference between the signals output from each of the multiple channels of the multi-channel receiver from the respective amplitude and phase data output from the multi-channel receiver fuzzy calculator to produce the same phase, And a demodulator for demodulating the digital signal output from the multi-channel receiver signal synthesizer.
