Real-time signal processor structure for two-dimensional synthetic aperture radiometer

The invention relates to a real-time signal processor structure for a two-dimensional synthetic aperture radiometer, which is used for realizing functions of the radiometer, such as multi-channel synchronous analog-to-digital conversion, high-speed data transmission, real-time related operation and the like. The structure is mainly characterized in that: by using the characteristic that a CPCI bus is divided into a PCI bus and a user-defined bus, a group of data acquisition plates, a timing control plate, a correlator plate and a single board computer are connected through the CPCI bus. A multi-channel high-speed serial bus is arranged in the user-defined bus to meet the requirement of high-speed transmission bandwidth among the data acquisition plates and the correlator plate; the timing control plate can send a synchronous signal to each data acquisition plate through the user-defined bus; and the single board computer is communicated with other board cards through the PCI bus and used for sending a scheduling instruction and reading an operation result.
