To realize the radar target RCS data compression and reconstruction over the hardware platform, based on threshold DFT （TDFT） algorithm, the base-2 FFT algorithm is used and the complex number multiplication of the computation sequence and the rotation factor of the improved ORDIC algorithm is applied to the butterfly computation portion. The probability of implementing the RCS data compression algorithm over the hardware is analyzed in theory, and the whole process of algorithm hardware implementation is simulated over Matlab in this paper. The simulation results show that the proposed algorithm of radar target RCS data compression and reconstruction method can be implemented over hardware, offering a certain reference for the hardware implementation of radar target RCS data compression and reconstruction.
