    Abstract: PURPOSE: The FMCW (Frequency Modulated Continuous Wave) radar signal process module and a memory management method thereof can save using memory resource. CONSTITUTION: The FMCW radar signal process module comprises a first FFT (Fast Fourier Transform) processor (11), a second FFT processor (12), and a CFAR (Constant False Alarm Rate) wave detector (13). The first FFT processor is connected to a second port of a double-port-memory (100), and after FFT-processing data stored in the double-port-memory through the second port, stores first data, which is FFT-processed, into the double-port-memory. The second FFT processor is connected to a first port, and it reads a first data through the first port, and after FFT-processing the first data read, stores second data which is FFT-processed into the double-port-memory. The CFAR wave detector is connected to the second port and detects a target by CFAR-computing the second data stored in the double-port-memory.
