Abstract

The invention discloses a device for recording multipath data in a radar test in real time and a method for realizing the real-time recording of the data, relating to the field of measurement and control. The invention solves the problem that the existing radar test is lack of a device for recording communication data in real time. An FPGA (Field Programmable Gate Array) control circuit of the device comprises n communication interface logic modules, a data processing logic module, a CF (Compact Flash) card storage control logic module, an E2PROM (Electrical 2 Programmable Read Only Memory) read-write control logic module, a main control logic module, an uploading control logic module, a USB (Universal Serial Bus) interface logic module, n paths of synchronization FIFO (First Input First Output) memories, a front end synchronization FIFO memory, a rear end synchronization FIFO memory, a write USB asynchronization FIFO memory and a read USB asynchronization FIFO memory. The device ensures that different data are orderly stored in a CF card, and prevents the storage from being confused; and a final sector number of valid data in the CF card is detected through the E2PROM memory to ensure that the data is accurately read, and a chip is controlled to upload the data by controlling a USB.

Description

technical field [0001] The invention relates to a method for recording multi-channel data in real time. It belongs to the field of measurement and control. Background technique [0002] Radar is often used as a missile-borne sensor and is installed at the end of the missile. When testing the radar, the test equipment needs to communicate with the inertial navigation system to analyze the environmental information sent by it; it also needs to simulate the function of the missile-borne flight controller, send control commands to the radar, and read and analyze the radar information in time Response to control commands; in addition, when the radar requires GPS guidance, the test equipment also needs to read data from GPS, and so on. [0003] Whether the communication data is correct or not is directly related to whether the whole test system can work normally. In order to be able to conduct a comprehensive detection of the radar, it is necessary to record the communication d...
