Line-of-sight reconstruction for faster homing guidance

A novel way to generate the signal required for homing guidance is to reconstruct the line-of-sight angle by combining seeker boresight error with an integrated rate gyro signal. The paper shows that line-of-sight (LOS) reconstruction allows reduced stabilization loop gain requirements over other guidance implementations. For a given stabilization loop gain, faster guidance system time constants can be achieved with LOS reconstruction, thus enabling the guidance system to achieve more accurate homing than other implementations.
