反坦克导弹尾焰对微波信号衰减的理论预估

PREDICTION OF MICROWAVE SIGNAL ATTENUATION BY AN ANTI-TANK MISSILE'S EXHAUST PLUME

提出了一种能预测反坦克导弹尾焰及其它导弹喷焰对微波信号衰减的计算方法和计算机程序，它可定量地计算出推进剂中碱金属杂质含量、尾焰后燃效应和微波入射方位等因素对微波衰减的不容忽视的影响，弥补了AEROCHEM程序和IACH程序的不足。计算结果与实验结果比较有较好的一致性。

Presents a computational approach and a consequent computer code for the prediction of microwave signal attenuation by a rocket,s exhaust plume from an antitank or other kind of missile. Significant effects of the amount of alkali-metal impurities in the propellant, magnitude of afterburning, and difference, in diagonal angles of mierowave beam upon the microwave signal attenuation can be calculated quantitatively using this code. The code can remedy the weaknesses present in the AEROCHEM and IACH codes. The computated results are in good agreement with those by experiments.
