Wide instantaneous dynamic range proportional signal processor

摘要

A proportional processing technique having a wide instantaneous dynamic range and providing a significant increase in instantaneous dynamic range over presently known proportional processing methods. These improvements are made possible by the use in accordance with this invention of a logarithmic amplifier in each channel of a pair of channels relatable to the same sensing plane. Each logarithmic amplifier is preferably arranged to operate substantially at the midpoint of its operating characteristic, and the pair of channels may be orthogonally related to another pair of channels, such that suitable guidance commands can be derived and furnished for example to a missile.
