IMPULSE RADAR TECHNOLOGY

THE OBJECTIVES ARE TO IDENTIFY EXISTING TECHNOLOGY APPLICABLE TO SUBNANOSECOND IMPULSE RADAR DEVELOPMENT. HARDWARE SOURCE WILL BE IDENTIFIED THAT MAY OFFER HIGH POWER, SUBNANOSECOND, PHOTOCONDUCTIVE SWITCHES AND FAST TRIGGER LASERS, LOWNOISE, VERY WIDEBAND, NONDISPERSIVE EM RECEIVERS, AND WIDEBAND NONDISPERSIVE EMITTER ELEMENTSUITABLE FOR MATCHING SUBNANOSECOND BASEBAND PULSE TO FREE SPACE RADIATION. THESE OBJECTIVES WILL BE DEVELOPED WITH COMPLEMENTARY INVESTIGATION INTO KEY ISSUES RELEVANT TO THE OBJECTIVES. KEY ISSUES INCLUDE THE FEASIBILITY FOR RECEIVER DEVELOPMENT, THE EFFICIENCY IN AN IMPEDANCE MATCH FROM ANTENNA TO FREE SPACE, THE ABILTY TO CREATE THE PULSE OFF-RAMP AS FAST AS ITS ON-RAMP, THE FEASIBILITY TO CONSTRUCT A TIMED ARRAY FOR OVERLAP AND STEERING, THE ADEQUACY OF POWER ON TARGET IN THE SUMMED PULSE, THE EFFICIENCY OF ENERGY CONVERSION, THE MATERIAL LIMITATIONS OF THE SWITCH DEVICE, AND LASER LIMITATION OF THE SWITCH DEVICE, AND LASER LIMITATIONS OF THE SWITCH DEVICE, AND LASER LIMITATIONS. THE PROJECT WITH BE PERFORMED BY NSSI TECHNOLOGIES TECHNICAL PERSONNEL WITH THE ASSISTANCE OF CONTRACT CONSULTANTS AT THE UNIVERSITY OF TEXAS, ARLINGTON. THE SCOPE OF EFFORT IS EXPECTED TO BE COMPLETED WITHIN THREE MONTHS.
