Abstract

A REQUIREMENT EXISTS FOR HIGH PERFORMANCE, COMPACT, LOW-COST, RELIABLE INTEGRATED MILLIMETER WAVELENGTH TRANSCEIVERS FOR TACTICAL WEAPON SEEKERS. SOME OF THESE SEEKERS REQUIRE A MONOPULSE TYPE TRANSCEIVER OPERATING IN W-BAND. DURING PHASE I A UNIQUE APPROACH TO SATISFYING THIS REQUIREMENT WAS INVESTIGATED WHEREIN THE FEED/ COMPARATOR PART OF THE RECEIVER WOULD BE REALIZED USING DIELECTRIC INSULAR WAVEGUIDE. RESULTS TO DATE VALIDATE BASIC FEASIBILITY OF THIS FEED COMPARATOR BUT ADDITIONAL EFFORT IS REQUIRED TO IMPROVE AND REFINE PERFORMANCE AND TO ESTABLISH PRODUCIBILITY OF THIS DEVICE. THE INITIAL PART OF THE PROPOSED PHASE II PROGRAM WILL ADDRESS THIS REQUIREMENT. THE SECOND PART OF PHASE II WILL DEVELOP AND DEMONSTRATE THE FULLY INTEGRATED W-BAND MONPULSE RECEIVER (LESS LOCAL AND TRANSMITTER OSCILLATOR). PLANAR INTEGRATED CIRCUIT TECHNIQUES WILL INCORPORATE IN A SINGLE MODULE THE CIRCULATOR, THREE BALANCED MIXERS AND THE LOCAL OSCILLATOR POWER DISTRIBUTION NETWORK. A COMPACT CONFIGURATION IS DESCRIBED WHICH WILL ACCOMODATE TO THE FORM FACTOR OF TYPICAL WEAPON APPLICATIONS. THE POSSIBILITY OF A GENERIC TYPE RECEIVER WHICH ADAPTS TO VARIOUS SYSTEM REQUIREMENTS BY ADDING APPLICATION SPECIFIC MODULES IS DESCRIBED.
