FPGA is used to convert fixed-point data to floating-point data. The data format processed by FPGA is generally fixed-point format. The disadvantage of fixed-point processing is that its dynamic range is small and the precision of pulse compression is low. However, radar requires high data precision and large dynamic range for signal. At this time, fixed-point signal processing will have the risk of data overflow. Floating point operation just can make up for the deficiency of fixed-point processing, because floating-point operation has improved in data precision and dynamic range.
