A high dynamic receiver of spread spectrum and precise measurement distance adopts the structure of a flexible field-programmable gate array plus digital signal processing to realize all-digital operation. The receiver mainly comprises two big modules: FPGA and DSP, wherein, the FPGA concretely comprises the design of hardware and software; the DSP module concretely comprises three components: a main program, an interrupt service program and a loop processing program. The high dynamic receiver of spread spectrum and precise measurement distance provided by the invention has the advantages of high precise measurement distance, high anti-interference ability in communication and accurate measurement and control.
