Paper Abstract

The problem for improving the temporal resolution of highly dynamic backscattering signals is important in the remote probing of the atmosphere. The use of inverse methods in lidar receivers is one of the novel approaches to improve their performance at arbitrary photon rates. In previous works we have developed a model of a lidar receiver based on the excitation of decayed oscillations in a set of resonators and the use of inverse algorithms for retrieving the lidar profile. In this work we present the experimental results obtained with the specialized receiving system developed according to the above model. It makes use of low frequency non-Fourier eigensignals of periods larger than the observation interval.It is shown that the profiles of electrical pulses may be resolved by 50 ns resolution at 10 frequencies below 1 MHz.
