Embodiment Construction
[0010] refer to figure 1 . In the following embodiments, the phased array antenna gain adaptive control implementation method includes, after receiving the target signal by the phased array receiving element, forming a pitch difference signal, an azimuth difference signal and a sum signal, and sending them to the frequency converter 1, Inverter 2 and inverter 3 perform down-conversion processing, and then send them to ADC1, ADC2, and ADC3 for sampling respectively, and then send them to the capture and tracker for signal detection. After the acquisition and tracker receives the pitch difference signal, azimuth difference signal and sum signal formed by the receiving antenna elements, it can obtain the azimuth angle and pitch angle information of the target relative to the phased array receiving antenna in real time by extracting the signal phase, which is the wave controller Controlling the beam pointing of the transmit phased array antenna provides the data. The acquisition...
