Passive ground-based sensor networks could bolster air, missile defense resilience: CSIS
Passive sensors do not need to emit energy to find and fix targets, thus, they are harder for adversaries to find, track and target.

Selling off the low S-band "is a terrible, horrible, no good, very bad idea," Tom Karako, director of the CSIS Missile Defense Project, told Breaking Defense today.
The radars would help modernize NORAD’s air defenses, though it’s unclear how the program may change due to strained ties between the US and Canada introduced by the Trump administration.
The upgrade allows existing radar warning receivers to analyze unfamiliar signals in real time — fast enough to warn the pilot if it’s an enemy radar locking on. “It could go on any kind of F-16” or a wide range of other aircraft, Raytheon Vice President Michael Baladjanian told Breaking Defense.
The language in the SASC version of FY25 NDAA demands that DoD detail what military systems have previously and currently have operated in, or in those adjacent to, "the 1525-1559 megahertz and the 1626.5-1660.5 megahertz" radio frequency bands at the center of the long-running DoD-Ligado dispute.
Dan Ceperley, the company's chief operating officer, told Breaking Defense that VLEO — typically defined as between 150 and 350 kilometers in altitude — is increasingly being used, including by Russia and China.
Hiding in the sun, launching mini satellites and radar absorbent materials are just some of the tricks nations are using to hide their military satellites in orbit.
