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.
