Abstract
A directional receiver is provided for an aircraft collision avoidance system. The receiver may include input channels that are configured to receive uncompressed linear analog signals from antenna elements that are arranged within a predetermined antenna element geometry. The receiver may further include Analog to Digital (A/D) converter modules, a quadrature converter module and a combiner module. The A/D converter modules can convert each of the analog signals to uncompressed linear digital data and output separate digital data streams that correspond to each of the input channels. The quadrature converter module can mix the digital data streams with corresponding digital reference signals to produce digital In-phase (I) and Quadrature (Q) streams.
