闪烁输入下比例导引系统无量纲化研究

Non-dimensional-normalization of PN System with Glint Input

研究了目标闪烁输入下比例导引系统的无量纲化,得到了在闪烁输入下比例导引系统的脱靶量与弹目相对运动速度Vr无关,与噪声功率谱平方根Ka和系统动力学无阻尼自振频率的平方根(ω_n)^(1-2)成正比的结论,这些结论在工程实用中具有重要意义。

Non-dimensional-normalization of PN system with glint input was studied. It is concluded that the miss distance due to glint input has no relation with the relative velocity Vr , but is proportional to the square root of undamped natural frequency of the system dominant lag √ωn and the square root of spectral density of the noise Ka o These conclusions will have a great significance in engineering applications for guided weapons.
