| 摘 要： | 提出了一种基于频率和时间多重相关的红外检测技术,即在原来通用的单一频率调制的基础上加上时间相关,使得各对探测点之间有确定的频率和时间关系.采用该技术组成的二维红外阵列检测系统可以抵抗直流红外辐射干扰以及相邻红外辐射源的干扰,从而使得采用高密度红外列阵的高精度检测成为可能.采用该技术的红外检测系统已经在公路车辆自动识别系统以及模拟雷场系统中得到成功运用,系统工作稳定可靠.

| Abstract: | The infrared detecting technique based on multi correlation of frequency and time is given. By this technique, time correlation is added to frequency modulation, and then there are certain frequency and time relation to every couple of detected points. The detecting system of this technique can resist the DC and the adjacent infrared radiation, there for the accurate infrared detecting is possible. This technique is applied successfully in the automatic vehicle classification system and the mine field simulator. |
