Numerical Deconvolution to Obtain Cloud Signatures from Scattered Light Pulses
Abstract
The optical return pulse resulting from light reflected from a cloud is given by a convolution of the transmitted pulse with the system range response and the cloud signature. To calculate the cloud signature when everything else is known requires a deconvolution. Since this deconvolution enhances noise, it is very difficult to get better resolution in the cloud signature than the 1 to 2 m that is immediately available by dividing the return pulse by the range response. (This relatively good resolution is available in this way because the transmitted pulse is fairly short, being about 6 ns FWHM.) It is shown that modestly improved resolution is possible if the signal to noise ratio in the return pulse is greater than about 100 to 1. (Author)
