Design and realization of electronics system of laser altimeter

The design and realization of electronic system of a laser altimeter based on active remote sensing technology is introduced.The matching filter technique is used to automatically acquire best signal-to-noise ratio(SNR) from different targets and to ensure the fidelity of the signal.Measurement of distance based on delay lines is used for the altimeter as a backup system.The experimental results show that the electronic system has fully achieved measurement accuracy and signal fidelity requirements.
