Abstract:When remote objects are detected by use of SAL, weak echo signal is easy to be interfered by noises. To obtain high receiving performance, the amplifier and signal processing system should be carefully designed. In this paper, the circuit consisting of the microwave filter, the pre-amplifier and the main amplier is designed under the condition of photodiode impedance matching. The major noises of PIN photo diode are analyzed and a low noise pre-amplifier circuit is designed,which can improve the signal to nois… Show more
