Maximum-likelihood multiresolution laser radar range imaging

Maximum-likelihood range imaging is considered for pulsed-imager operation of a coherent laser radar. The expectation-maximization (EM) algorithm is used to develop an explicit procedure for maximum-likelihood fitting of a multiresolution (wavelet) basis-at a sequence of increasingly fine resolutions-to laser radar range data. Specialization to the Haar-wavelet basis yields a procedure that is ...

Long range , high resolution laser radar

Initial laser radar experiments used CO* gas lasers at 10 pm [ I]. These lasers enabled either stable cw operation or high-gain pulsed output and have been used for wind measurements in the atmosphere. Despite the success of COz lasers, there has recently been an increased interest in the use of solid state, 1 urn laser technologies to be used for laser radar studies. The advantages of such a s...
