| Abstract: |
| A digital acquisition interface module for radar signals is described which is realizated by using CPLD M4A5 - 128/64 and DSP TMS320VC5402. The functions and specifications of main devices used are introduced. The level convert circuit of triggering pulse signal and ship heading signal, and radar video signal A/D convert circuit are also discussed. The CPLD logical design and DSP software design is presented. |
