摘　　要：本文研究了在直角或极坐标系建立测试ＨＤＴＶ图像质量用多种测试图、卡之数学模型的原理和方法；定量分析了各模型参数的计算方法；按测试需要所设计的这些测试图、卡可用ＶＡＸ机和通用微机生成；它们可直接用于ＨＤＴＶ计算机模拟系统，设置接口。In this paper, the principle and the method for developing the mathematical models of various test patterns and test cards in rectangular coordinate system and polar coordinate system are presented.And then the method for calculating the model parameters is quantitatively analyzed. The test patterns and cards are designed according to the test need and are also generated on VAX or microcomputer. They can directly used in the simulation system of HDTV. Forthermore, through necessary interface circuits, they can be used to test real HDTV systems or equipment.
