Theoretical Analysis of Scanning and Identifying Cat-Eye Target with Coherently Combined Array Gaussian Beams

Influence of atmosphere turbulence and laser coherence on the identification method based on interference multiple-beam scanning of optical targets

“…Our studies represent a much more broader and deeper version of the work done by the authors of Ref. [8]. In contrast to the earlier literature data, we have obtained more practical results.…”

“…[8], the time distribution of the reflected beam is not periodic whenever diffuse objects are scanned by a combined beam, which is equivalent to a single-beam scanning condition. So the main emphasis of our research is a combined-beam scanning of optical objects.…”

“…2 in Ref. [8] and by the Collins formula, the cross-spectral density function of the GSM beam reflected by optical target reads as…”

“…[8,9]. Using this method, space distribution of the reflected light can be transformed into measurable time series, whose periodic characteristics can be used to identify some optical characters, e.g.…”

“…The main assumption made in Ref. [8] rests on the conditions of no turbulence available and a great coherence of laser beam. Only preliminary laboratory experiments have been performed in this direction [9].…”
