Abstract: In order to carry out scientific research on radar astronomy, the radar echo signals received by the radio telescope are collected and recorded, and the radar astronomy baseband data acquisition and recording system is developed based on the SNAP (Smart Network ADC (Analog to Digital Converter) Processor) hardware experiment board and fast storage server. The system adopts the graphical FPGA (Field Programmable Gate Array) development tool flow provided by CASPER (Collaboration for Astronomy Signal Processing and Electronics Research), and designs dual-channel, 256 MHz bandwidth signal acquisition and VDIF (VLBI (Very Long Baseline Interferometry) Data Interchange Format) baseband data output firmware program; based on the HASHPIPE (High Availability SHared PIPeline Engine) multi-threaded management engine, a real-time baseband data storage program with dual 10 Gigabit Ethernet ports was developed, with a storage bandwidth of 1GB/s; finally, a conversion program from VDIF format to radar astronomy format was written. After the pulsar signal observation experiment, the system is accurate and reliable.
