毫米波系统具有全天候或低能见度条件下工作的能力,但毫米波被动探测图像的限制是分辨率。维纳滤波是对退化图像进行有约束处理的一种有效算法,文中给出了毫米波被动探测装甲目标的维纳滤波去噪。为进一步刻画毫米波被动探测目标辐射的表征方法,在分析毫米波被动探测能力的基础上,建立了目标毫米波被动探测辐射截面分辨能量体的新概念,并给出3mm被动辐射计探测单层隐身迷彩装甲目标的辐射截面能量分辩体的实测与分析研究。

Passive millimeter wave sensor has the advantages in all weather detection or low visibility conditions of work. But the images blur is still a problem. Wiener filtering is restricted on the degenerate image processing is an effective algorithm; it was utilized for the millimeter wave passive detection armor target de noising. To study of the radiation characteristics of the armored target, it was established that target radiation cross section distinguish energy body as a new concept based on the analysis of the ability to passive millimeter wave radiometer detection. The experiment of the coating-stealth material target with 3mm radiometer was given and the radiation cross section distinguish energy body was analyzed.
