For the receiver tests, the method includes receiving the RF signals at receiver channels over propagation paths corresponding to the probe antennas, where each of the receiver channels is set at a selected complex gain setting of multiple available complex gain settings; measuring a combined receive signal output from a single combined output of the phased array antenna; isolating complex gain and complex path loss products from the measured combined receive signal corresponding to the selected complex gain setting and the propagation paths at each of the receiver channels; and determining a relative value between the complex gain of one receiver channel and previous complex gain of the one receiver channel using the isolated complex gain and complex path loss products."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for determining relative complex gain of channels in phase array antenna","description":"A method is provided for performing receiver and transmitter tests of a phased array antenna using a test system including probe antennas for transmitting and receiving RF signals, respectively.
