Abstract

Monitoring the coherence of the fully coherent mode of distributed coherent radar (DCR) is an important problem. Two algorithms are given to monitor the coherence based on the signal-to-noise ratio (SNR) gain. The first algorithm was designed for architectures with one transmitter and multiple receivers, where a one way waveform can be obtained directly from any receiver to monitor the SNR gain. The second monitoring algorithm was designed for architectures with multiple transmitters and one or multiple receivers, where the baseband signals of all the transmitters are the same, so all received signals at any receiver are superposed together and a one way waveform cannot be obtained by matched filtering. An auxiliary antenna technique is given to monitor the SNR gain with numerical simulations showing that the two algorithms are in general effective.
