With the trend that cruise missiles aim at high efficient attack and intelligent enhancement, only using DSP software to process images cannot satisfy the higher real-time requirements for terrain matching and target recognition. Therefore, according to the advantage of FPGA implementation on computation accelerating, this paper proposes a simplification method for the normalized product correlation algorithm formula, which has the characteristics of high precision and high speed, and designs the product correlation’s hardware acceleration unit and multi-channel parallel computing architecture. FPGA implementation verifies that the proposal can satisfy the real-time requirements for terrain matching and target recognition of the new generation of cruise missiles.
