Abstract

Millimeter-wave thermal imaging provides a unique autonomous capability for aircraft landing in adverse weather, giving a pilot a comprehensive view of runway location and availability in real time with high fidelity. ThermoTrex Corporation has reported previous results from a passive millimeter-wave camera demonstration device. The addition of W-band low-noise amplifiers into the front end of this sparse phased-array thermal imaging camera has improved system thermal sensitivity by 5 dB over that previously reported. Processing upgrades have increased system frame update rate to about 1 Hz, and remote site field testing has established phenomenology relevant to aircraft landing guidance applications. Next-generation hardware design has addressed the issue of aircraft integration using an innovative lightweight, X-band antenna for 89 GHz thermal imaging. A flightworthy demonstration imager using this antenna is currently under construction for 10 Hz operation.
