摘要
针对平面金属和装甲目标被动探测信息特征相似,在现实战场上极易造成真假目标错判的问题,提出了利用目标与背景的辐射温度对比度,结合金属目标的毫米波辐射特性新表征概念——辐射截面(RRCS)的识别装甲目标方法。该方法利用探测背景下目标的辐射温度差异,乘以目标面积得到目标的辐射截面,最后根据目标RRCS的均方根误差比值来进行目标识别判断。对不同背景地物样本的RRCS均方根误差比值计算分析结果表明,在相同条件下,可以利用RRCS均方根误差比值的比较有效识别出装甲目标。
Since the passive detection information feature of planar metal is similar with that of the armored target, it is very easy to make wrong judgment on true or false target in the real battlefield. To solve the problem, a method for armored target identification is proposed by using the radiation temperature contrast between the target and the background, together with the new characterization concept of millimeter wave radiation characteristics of the metal target, i. e. , the Radiometer Radiation Cross Section( RRCS). The method utilizes the difference of the radiation temperature of the target in the detection background, which is multiplied with the target area to obtain the target radiation cross-sectional area. Finally, the target recognition judgment is performed according to the Root Mean Square Error( RMSE) ratio of the target RRCS. The results for samples under different backgrounds show that: under the same conditions, the armored target can be identified more effectively by using the comparison of the RMSE ratio of RRCS.
