COMPARISON OF 3 mm AND 8 mm WAVEBAND PASSIVE DETECTION
3mm与8mm波段无源探测特性的比较

The principle of mmW passive detecting cement roads was studied.According to the antenna,surface feature and radiometer characteristic of 3-mm and 8-mm waveband,the antenna temperature contrast and the maximal detecting distance of 3-mm and 8-mm radiometers were obtained by different antenna diameters and working conditions.Also,the actual detection effect of these two models was compared.
