固定单站对机动红外辐射源的无源定位研究

Single Passive Location and Tracking Theory for Maneuvering Infrared Emitter

文章在现有单站无源定位技术的基础上,介绍了一种根据红外辐射在大气中的传输特性,提出机动空中辐射源的单站无源定位方法,并且给出了它的EKF型的直接递推估计算法,通过计算机仿真验证了该方法的正确性及有效性,该方法可应用于抗低空突防和反隐身目标的空防系统中。

The technology of single observer-passive location for maneuvering emitter in the sky such as battleplanes, missiles and rockets has significant martial importance and prospects for application. A technology of single observerpassive location for maneuvering emitter is introduced based on existing methods according to transmission characteristic of infrared radiation in the air. And the algorithm of Extened Kalman Filter（EKF） is applied to the method. With the help of computer simulation, the method is proven to be correct and effective. The method can be applied to the antiaircraft system against covered target and low altitude breakthrough for defence.
