It should be for the landing radar on the vehicle. It's the same frequencies on the Falcon 9 RTLS permits. That is the normal use of those frequencies:Quote4200–4400 MHz Band. This band is allocated on a primary basis for aeronautical radionavigation where its only use in this band is for aircraft radar altimeters.

The Federal Aviation Administration (FAA) prepared a Draft Environmental Assessment for SpaceX Falcon Launches at Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) (Draft EA) for public review. SpaceX is applying to the FAA for launch licenses to launch the Falcon 9 and Falcon Heavy from KSC Launch Complex 39A (LC-39A) and CCAFS Launch Complex 40 (LC-40). SpaceX is also applying to the FAA for reentry licenses for Dragon reentry operations. Public comments on the Draft EA are due by March 20, 2020.Under the Proposed Action addressed in the Draft Environmental Assessment (EA), the FAA would:* Issue launch licenses to SpaceX for the Falcon 9 and the Falcon Heavy from Kennedy Space Center (KSC) Launch Complex 39A (LC-39A) and Cape Canaveral Air Force Station (CCAFS) Launch Complex 40 (LC-40).* Issue reentry licenses to SpaceX for the Dragon vehicle.
Dragon Recovery vessel, Atlantic Ocean recovery zone and a new mobile launcher are part of some bigger plans from @SpaceX faa.gov/space/environm…images: SpaceX

This STA is intended to cover pre-launch testing for a commercial payload on mission 1423. Tests involve fairing re-rad operations at Pad 40 at Cape Canaveral AFS or Pad 39A at Kennedy Space Center, and stand-alone testing at the SpaceX Payload Processing Facility. This STA is not for flight.
You are advised that the Commission is unable to grant your application for the facilities requested. NTIA objected due to anticipated harmful interference to federal space operations.
When a permit request is submitted, it gets run by NTIA as a federal clearinghouse to see if anyone has a problem with the location/frequencies being used. If someone, somewhere in the government does have a problem, it gets denied. And it's kinda like a compiler from an old programming language that just tells you that your code didn't run. They don't actually say what the problem with the application is. Blue Origin just went through a similar situation with permits at their Texas site and it was really ridiculous.

Blue Origin just went through a similar situation with permits at their Texas site and it was really ridiculous.This is the inverse of "Bring me a rock." (A cliche for bad review process.) "That rock is unacceptable." But we learned more about the New Shepherd issue, and read Blue's response, which was asking the FCC to pick a couple of frequencies that would be OK.Blue said that they didn't need all of the possible frequencies they had asked for.They were told that some of them might interfere with law enforcement, which was more than just "no go".Did Blue get that response telling them which frequencies to use?Did they get the issue resolved and the flight permitted?How did SpaceX respond?
Blue Origin finally got their FCC permits for New Shepard flight 13. After their application from Dec. 9 was denied, they tried again on Dec. 20 by filing individual permits for each of four frequencies. They managed to get two of the four approved. The date range is February 1 through March 15. 2382-EX-ST-2019 2385-EX-ST-2019
