76 GHz under threat from car radar

The ARRL reports the Amateur Radio and Amateur Satellite allocations
in the 76 GHz band are under threat from vehicular radar systems

The FCC is seeking comment on issues involving expanded use of various
radar applications in the 76-81 GHz band, which Amateur Radio shares
with other services. The band 77.5-78 GHz is allocated to the Amateur
and Amateur Satellite services on a primary basis, and to the Radio
Astronomy and Space Research services on a secondary basis.

“We undertake this proceeding to expand the available spectrum for
radar operations in the 76-81 GHz band,” the FCC said in a detailed
Notice of Proposed Rulemaking and Reconsideration Order (NPRM&RO),
released February 5 in ET Docket 15-26. The Commission said the
proposals include allocation changes as well as provisions “to ensure
that new and incumbent operations can share the available frequencies
in the band.”
