The invention provides a double-code-stream network radar data acquisition unit and a data acquisition method. The double-code-stream network radar data acquisition unit comprises an analog signal conversion circuit, a digital signal receiving circuit, an AD acquisition circuit, a main control circuit and a network driving circuit, the analog signal conversion circuit and the AD acquisition circuit convert an analog video into a parallel digital signal, and the parallel digital signal enters an FPGA of the main control circuit; the digital signal receiving circuit receives the radar state signal and then sends the radar state signal to the FPGA processor; the FPGA processor analyzes the radar data and divides the radar data into a main code stream and a sub code stream for data processing, and the processed data is stored in the DDR3; and the ARM processor respectively compresses the double-code-stream data in the DDR3, and then sends the double-code-stream data to an external network through the gigabit network driving circuit. According to the double-code-stream network radar data collector, a large amount of radar data preprocessing work can be processed, and the double-code-stream function meets the multi-scene and multi-terminal control requirements of a user.
Description
technical field [0001] The invention relates to the technical field of radar signal processing, in particular to a dual-stream network radar data collector and a data collection method. Background technique [0002] At present, in the field of radar applications at home and abroad, X-band and S-band magnetron radars or solid-state radars are usually used in shore-based detection radars and marine navigation radars. Due to the long deployment years of these radars, most of the radar signals use analog signals from the antenna. It is said that the interface standard does not agree, and the supporting radar processor needs to perform signal processing and analog-to-digital conversion, and display it by the display and control equipment, while the radar manufacturer will only configure one processing and display control equipment for a single set of radar. [0003] With the popularization of mobile communication devices such as mobile phones and PADs, and the development of mult...
