| 摘 要： | 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。小波包消噪是对退化图像进行处理的一种有效算法,给出了毫米波被动探测装甲目标的小波包分析去噪。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3 mm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辨体的实测与分析研究。

| Abstract: | Passive millimeter wave sensor can work in all-weather or low-visibility conditions.But the image blur is still a problem.Wavelet packet de-noising is an effective algorithm for processing the degradation images.It was used for de-noising in armored target detection with passive millimeter wave.To study the radiation characteristics of the armored target,the passive detection capability of passive millimeter wave radiometer was analyzed,and a new concept of target radiation cross section distinguish energy ... |
