É descrito um método para calibração rápida de antenas de conjunto de recepção de formação de feixe digital (DBF) por meio de processamento de sinal digital. Ele usa ondas planas que chegam de uma direção conhecida que contém uma sequência de referência conhecida. As não uniformidades de amplitude e fase nos ramos são detectadas e calibradas em tempo real pela correlação complexa de uma réplica da sequência de referência conhecida com o sinal recebido obtido dos sinais de saída de cada elemento. Nenhum circuito especial para calibração é necessário e as não uniformidades podem ser rapidamente compensadas pelo processamento de sinal digital, mesmo para um conjunto de antenas com muitos elementos de antena. Este método permite a calibração altamente precisa de antenas de grande escala operando em alta frequência, mesmo sob uma baixa relação de potência sinal-ruído (SNR).

Abstract: A method for fast calibration of digital-beam-forming (DBF) receiving array antennas by means of digital signal processing is described. It uses plane wave arriving from a known direction that contains a known reference sequence. Non-uniformities of the amplitude and phase in the branches are detected and calibrated in real time by the complex correlation of a replica of the known reference sequence with the received signal obtained from the output signals of each element. No special circuit for calibration is required, and the non-uniformities can quickly be compensated for by digital signal processing even for an array antenna with many antenna elements. This method enables highly accurate calibration of large-scale array antennas operating at a high frequency even under a low signal-to-noise power ratio (SNR).
