Technology of Array Signal Processing for Large Phased Arrays Based on Muti-beam Position Search
Digital beam forming technology is a key in the field of communication countermeasures.By controlling the signal amplitude and phase in the digital domain,multiple independent and controllable beams can be formed,with high precision and flex-ibility in beam pointing,and theoretically not limited by the number of beam forming.The article focuses on the requirements of large phased arrays,utilizes the principle of digital beam forming,and combines large-scale arrays signal synchronization technolo-gy and phased arrays amplitude-phase calibration technique,implements a multi-wave position beam search system that can simulta-neously generate 180 biased beams.It can utilize the real-time scanning function of the beam group to achieve large-scale beam search and faster target angle positioning.The system has been applied in engineering and successfully executed a large-scale mea-surement and control task,achieves complete success.
