一种由舰艇发射,攻击敌舰艇的导弹,其上装有被动式雷达导引头。由于安装有导引头,应属于两位置导引法。两位置导引法中比较理想的导引规律是比例导航法。本系统采用被动式导引头加前置陀螺,较好地实现了比例导航法,使得弹上设备大大简化。但由于弹上没有测量弹速方向的装置,又使得导引精度受到一定的影响。一、导引方法导弹发射后,导引头开始工作,此时导弹已完成爬高阶段。利用高度表使其保持在距海面30米高度上平飞;尔后,平飞高度降为8米,直到与目标相撞。弹上制导设备取消了俯仰 A missile fired by a ship and attacking an enemy ship with a passive radar seeker mounted on it. Due to the installation of the seeker, it should be a two-position guidance method. The ideal guide law in two-position guidance method is the proportional navigation method. The system uses passive seeker plus pre-mounted gyro, a better implementation of the proportional navigation method, making the device greatly simplified on the bomb. However, because the projectile has no measure for the direction of the projectile, it also affects the guiding accuracy to a certain extent. First, the guidance method After the launch of the missile, the seeker began to work, this time the missile has completed the climb phase. Use the altimeter to keep it leveled at a distance of 30 meters from the surface of the sea; thereafter, the level flight is lowered to 8 meters until it collides with the target. Guided missile on the missile canceled pitch
