六十年代初期人们就已经注意到,高速飞行器重返地球大气层,由于剧烈的气动加热,头部周围的空气及烧蚀产物电离,形成等离子鞘和电离尾迹。等离子鞘影响再入通讯,电离尾迹使地面雷达容易发现目标,对突防不利。设法消弱真目标电离尾迹,即设法减弱尾迹中的电子密度以使敌方雷达难于“捕捉”和设法增强假目标电离尾迹以诱惑敌方雷达,是一个 It has been noticed in the early 1960s that the high-speed aircraft returned to the Earth’s atmosphere and ionized due to the intense aerodynamic heating of the air and ablation products around the head to create a plasma sheath and ionisation trail. The plasma sheath affects reentry communication, and the ionospheric wake makes ground-based radars easy to find the target, which is unfavorable to the penetration. Trying to weaken the true target ion trail, which seeks to weaken the electron density in the wake to make it harder for the enemy radar to “catch” and to try to enhance the pseudo-target ion trajectory to seduce the enemy radar, is a
