The invention discloses a radar signal acquisition regenerator which comprises an acquisition device and a regenerator. The acquisition device comprises a triggered pulse control module, a transmitter, a receiver, an ADC module, a signal processing and acquiring module, an image processing module, an acquisition comprehensive control module and an acquisition display unit. The regenerator comprises a regeneration display unit, a regeneration comprehensive control unit, a regeneration module, a DAC module and a video amplifier. The radar signal acquisition regenerator simplifies using of the product as possible, thereby realizing no excessive adjustment and facilitating data use and acquisition by personnel of different programs. After the data are acquired, the acquired data are used for analysis and testing by a background laboratory, thereby greatly reducing testing time of developing personnel, reducing development cost and improving developing efficiency. Through acquiring variouskinds of echo data in different environments, verifying and debugging on a signal processing algorithm and the like in the laboratory can be realized, thereby greatly reducing strength and working difficulty in radar outfield testing, reducing developing cost and improving working efficiency.
