Significant function of sensor signal processing system in airborne missile is analyzed. A new type of sensor signal processing system CGQSPS2 is designed. The system integrates many functions in a circuit board such as driving and signal conditioning

acquisition and digitally encode of several kinds of sensors. Compared with previous design

it reduces power consumption

saves space and cost

at the same time

improves precision of sensor signal acquisition

capability of resisting disturbance and system reliability. The system is successfully used in airborne missile

realize digital transmission of sensor signal and its function is validated.
