A parallel pipelined CORDIC-based matched filter coefficients weighted algorithm for frequency domain digital pulse compression (DPC) system is proposed. Unlike the conventional matched filter weighted methods based on look-up table, this design completes weighted process using circular mode CORDIC algorithm by controlling the input angle. The multiplication of the expansion factor is realized by finite additions which decreases the hardware cost. Compared with traditional methods, this proposed design saves hardware on multipliers, memories and improves the flexibility of the DPC system. The results of simulation show the proposed algorithm's efficiency.
