An experimental breadboard model of such processor based on the multichannel acoustooptical modulator intended for processing ofradar signals is described, results ofmathematical simulation and experimental investigations are presented.
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
