<title>Computation accuracy of optoelectronic array image processor for synthetic aperture radar (SAR) system</title>

Abstract

Mathematical model of optoelectronic image array processor for SAR system is described with consideration for disturbing factors which are present in real optoelectronic I such as noise and errors of 1 ight sources and photodetectors, ADC noni inearity and point spread function of the opti cal system . Analyti c formulae relating processor accuracy to the value of error probabi 1 ity and accuracy parameters of its processor elements as wel 1 as opti cal system qual ity are del ivered , The obtained theoretical results are closely approximated with modern experimental data. I . INTRODUC1ION. Nowadays different modifications of optoelectronic matrix-vector multiplier (OMVM) are appi ied to the 1 inear-algebra problems , spectrum analysis of radio signals, organization of reconfigurable interconnections, digital multiplication, neural networks' . One of the most promising ONVM appl i cations i s paral lel signal process ing in syntheti c aperture radar 2 Nevertheless , the advantages of arch itecture (Fig. 1) includes dynamic-vector input device (DVID), comprising linear array of light sources or 1-D SLN; optical system, projecting the image of the input O-8194-1843-9/95/$6.OO SPIE Vol. 2490 /325 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/24/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx
