| 针对日益增强的船舶自动识别系统（AIS）信号侦察需求，以实
时解调为主要侦察手段，结合采样数据存储，提出了一种通用的AIS信号侦察的FPGA设计方
案。通过乒乓操作、高精度计时器等设计，解决了AIS侦察的实时解调、标准时隙校准、高
精度时标等问题。试验结果验证了该设计的实用性。 |

| Abstract: |
| According to the growing ship automatic identification system(AIS) signal reconn
aissance demand, by using real-time demodulation as the main reconnaissance meas
ure, and in combination with the sampling data storage,a general FPGA design of
AIS signal reconnaissance scheme is proposed.Through ping-pong operation and hig
h-precision timer design,such problems as the real-time demodulation of the AIS
reconnaissance, calibration for standard slot and high-precision time scale are
solved. The feasibility of the scheme is verified by test. |
