"AAI and military are testing sense-and-avoid cameras that use polarized light to identify objects, cameras are embedded in the UAV wings."

Stephen Carlson commented on Paul Mace's blog post Air collision fears slow expansion of US drone use"I had been thinking about the sense and avoid issue, and I had settled on the idea of passive transponder "ping" detection around the 1060Mhz range where they operate. But recently, I've had the idea of just listening for aircraft…"

Paul Mace commented on Garry Qualls's blog post Groundstation Display Suggestions?"There is no good answer right now. You need 1000 nits, and/or transreflective tech. Xenarc makes 7' external VGA touchscreen monitors that qualify. But it's another piece of equipment and needs its own ciggie power and another cord. When…"
Paul Mace commented on Paul Mace's blog post Air collision fears slow expansion of US drone use"...and yes, let's not forget doppler/sound signatures, which could be very effective--at anything less than transonic airspeeds."
Paul Mace commented on Paul Mace's blog post Air collision fears slow expansion of US drone use"RF advantage is transparency to weather and to host aircraft [when antenna properly positioned]. Solution may incorporate other sensors [while obtaining 3D view adds cost and complexity] but must include at least passive RF. [Fly-Baby Bob emits lots…"
Mike Bakula commented on Paul Mace's blog post Air collision fears slow expansion of US drone use"That's true. But (short of a catastrophe that could have been avoided by universal transponder usage,) FAA isn't going to give up on the sense and avoid concept. So it's up to us to figure out how to see Bob, gliders and other…"
"As a glider pilot who flies in the Reno, Nevada area, I'm acutely aware of this problem. We operate at up to 18000 feet (and in certain designated areas, even higher), and due to the lack of an engine-driven electrical system, we are not…"

The salient line is "until the pilotless aircraft gain the high-tech ability to sense and avoid commercial aircraft and other airborne objects, the government is unlikely to allow them to operate much more freely in congested airspace."
