摘要
电子目标模拟器已广泛应用在电视跟踪系统的性能检测中。介绍了一种新型的电视跟踪系统目标模拟器,该模拟器的硬件平台由USB模块、FPGA模块和视频D/A模块搭建而成。在此硬件平台基础上,通过编写Verilog硬件描述语言仿真并模拟出满足被测电视跟踪系统测试需求的模拟目标图像。重点讨论了静、动态模拟目标的生成及其在性能指标测试中的应用。该目标模拟器集成度高、扩展功能强。
Electronic target simulator has been widely applied in performance test of TV tracking systems. A new target simulator is introduced. Its hardware platform consists of USB, FPGA and video modules. On the basis of this hardware platform, the emulated target image satisfying the needs of TV tracking system under test is simulated through programming Verilog hardware description language. The generation of static and dynamic simulated target and the application of the target in testing performance index are discussed emphatically. The target simulator features high integration and expandability.
