Teqnovations proposes to develop a versatile, high-power, 0.435 - 30 GHz active, modular, electronically scanned array (AESA) Emitter to replicate radar threat emitters. The AESAs combine ultra-wide bandwidth PUMA antenna elements with RF LC time-delay units (TDUs) to realize timed-array antennas. The Emitter comprises three ultra-wide bandwidth antennas mounted on a 6 x 6 radiating surface. Their frequency bands overlap to support modulation near their band edges. The two highest frequency antennas form 10 degree beams in azimuth and in elevation. The lowest frequency antenna beam widths are limited to 21 degrees in azimuth and 47 degrees in elevation limited by the size of the radiating surface. All three antennas scan beams 45 degrees in azimuth and in elevation. The rugged Emitter is designed for transport over dirt road commonly encounter in airborne vehicle test ranges. During the Phase I Base assess the feasibility of realizing a versatile, ultra-wide bandwidth, Emitter to emulate threat radar signals in a test range environment. In the Phase I Option we will improve the manufacturability of the TDUs to reduce SWaP and cost.
Benefit: The Versatile Emitter will obviate the need to make or buy unique threat radar system to evaluate airborne vehicles on test ranges. It will reduce the cost of test facilities and the time it takes to field a new threat emulator. Future radar and data communication systems may also benefit from technology developed under this program.
