Patria has a new passive radar out. That's great but what happened to the USAF giving us air dominance?

The passive radar is invisible to the enemy

Patria MUSCL can provide 360-degree surveillance up to hundreds of kilometers away, making it well-suited for air surveillance and border control. Surveillance can also be focused on a specific target to protect critical infrastructure. 

– The main advantage of the passive radar system is that it does not produce any signal trace itself. Thus, Patria MUSCL is practically invisible to enemy signal intelligence, says Aaro Malila, Product Manager at Patria. 

The signals sent by traditional radars immediately reveal their operation and location to the enemy's electronic surveillance sensors. In the worst case, it can take only a few seconds to locate, after which the enemy can target the radar with electronic jamming or direct fire.

Advanced signal processing detects targets

Patria MUSCL utilizes existing radio signals in the environment for its measurements. Typically, these are broadcast signals from radio or television stations. By using these, the radar can calculate the location and movement of an airborne target by comparing the signals reflected from the target with those that have traveled directly. 

The system can simultaneously track over a hundred targets.

– Due to its operating principle and low frequencies, Patria MUSCL has better capabilities to detect stealth targets compared to traditional radar, Malila notes. 

The shapes and surfaces of stealth aircraft are designed to scatter the signals of traditional surveillance radars so that they do not return to the radar receiver. In the case of Patria MUSCL, since the radar receivers are located in different places than the transmitters, scattering the reflections away from the transmitter does not provide as much benefit.

– The ability to detect stealth aircraft is improved by the fact that Patria MUSCL also utilizes signals with lower frequencies than traditional radars, Malila explains.

This is all well and good but what happened to the vaunted air dominance that the USAF provided.

Oh and don't be fooled.  The USAF has played a role in killing several US Army anti-air systems.  The reason?  If it flies the USAF would kill it.

I'm sure someone knows the new paradigm cause I don't.

Are ground forces now told to protect themselves from anything below 2K feet to the ground?

If so then what about surface skimming cruise missiles?  Drones I get but the bigger ones that fight at distance fly at the same altitude as jets?  Is there a dedicated aerial platform designed to hunt down loitering drones etc...
