Abstract

Developed in our previous works the concept of the multichannel correlator for SAR system picture forming device has been realised in the form of sandwich type opto-electronic chip, containing 3 layers of 2D optically connected optoelectronic devices: LED array with 64 strip shaped elements, fixed or adjustable mask and the 288x232 pixels CCD photomatrix, that is a 64 channel 288 steps correlator. Each channel of the processor forms one range resolution channel thus giving the opportunity to obtain at the output of the device the line of the synthesised SAR picture. In order to enhance range channel number, several chips, connected in appropriate architecture, should be used. SAR picture processor architecture and experimental results are discussed.
