Paper Abstract

Frequency-scanned slotted-waveguide and microstrip travelling-wave arrays, for detecting mm-wave (10-110GHz)thermal emissions via acousto-optic Bragg cell processors, are being considered in defence and civilian security-related remote sensing applications. The optical processing of RF signals is significant because it promises affordable RF operating staring multi-beam arrangements. Optical processing circumvents the need to assemble expensive miniaturised RF receiver elements in phased array configurations by allowing RF information to be processed using optical-video and CCD techniques. This paper considers the design and fabrication of microstrip travelling-wave based sensors for Ka (~35 GHz) -band operation.
