Experimental German radar 'tracked two U.S. F-35 stealth jet for 100 MILES' after lying in wait on a pony farm to catch them flying home from airshow
  • Radar is designed with sensors and processors capable of tracking F-35 jets
  • It works observing electromagnetic emissions in the atmosphere
  • Then it will read how signals are bouncing off airborne objects
  • German radar maker said the system tracked two US jets for nearly 100 miles

The F-35 stealth fighter is lauded by the U.S Air Force as almost invisible to radar - which is why it has spent $100 million on each of the jets.

However, a German radar maker claims to have tracked two of jets from a pony farm for nearly 100 miles using an emerging generation of sensors and processors.

It used a new 'passive radar' system that analyzes how civilian communications - such as radio and TV broadcasts and mobile phone stations - bounce off airborne objects.

This, the firm says, renders the jet's stealth technology, that is designed to absorb ground based radar to stop it reflecting back, redundant.

The new radar has no emitters so pilots do not realize they are entering a monitored area - but it relies on there being civilian communication waves.

The two F-35s were reportedly tracked in 2018 after being flown to Germany from Luke Air Force Base in Arizona for the Berlin airshow.

The jets never took to the skies during the show meaning that the passive radar, based in a corner of the airfield, could not be tested on them.

But the radar makers kept a watch on the F-35s and once they knew the jets gearing up to head home, they set up the system, called TwInvis, at a nearby pony farm.

Following the jets' take-off, the firm activated the radar, began tracking the jets and collected data using signals from the planes.

Stealth technology has provided fighter jets with the ability to elude radar defenses and the US has poured hundreds of billions of dollars into studying and developing aircraft with this capability,

However, it seems they may be returning to the drawing board after following the news that two of their F-35 fighter jets were tracked by a German firm, first reported by C4ISRNet.

he technology is designed to observe electromagnetic emissions in the atmosphere, which includes such signals from radio stations, televisions, cellphone towers and more.

The radar can then spot an aircraft by ‘reading how the signals bounce off’ of the jet.

It was reported that the two US Air Force F-35As were at the Berlin Air Show in 2018 where the data was captured.

The technology found the jets and tracked them for approximately 93 miles.

However, C4ISRNet also noted that the German company knew when the jets were coming and were able to use the signals from the jets’ ADS-B transponders to help identify the craft.

So although this may sounds troublesome for those flying into battle, real enemies will not know when these fighter jets are coming – so they may not be able to detect them without this knowledge.

Another issue is that the radar's ability to spot the jets relies on signals from civilian transmitters, and many war zones are wastelands with not a civilian in sight.

With this being known, nations with a stealth craft could easily take out cell phone networks through cyberattacks or bomb radio broadcasting towers to keep their fighter jets hidden.

However, TwInvis is the only one of its kind that has successfully tracked an F-35, and from 93 miles away.

'As the radar develops and operators refine their tactics, it could become even more effective,' Popular Mechanics reported.

F35 gone.
If the germans can do it so can others.
Had Germany ordered f35

Germany, France and Spain together are building a new next gen jet instead of going with the F-35

It is all to do with the German airforce wanting F35s and the German goverment wanting Typhoons for jobs, for the next round of purchase for their airforce.

Politics..

There is nothing extraordinary about this. What these people claimed to have is a bi-static radar. See Kolchuga and Lockheed's Silent Sentry. The problem is that the bi-static radar is not the solution to 'stealth' as everyone in the past made it out to be.


  • It works observing electromagnetic emissions in the atmosphere
  • Then it will read how signals are bouncing off airborne objects
To start, let us establish the foundation of a bi-static or so called 'passive' radar system...

In a bi-static radar system, there are multiple transmitters/receivers. The original configuration have multiple transmitters and one base receiver. With modern technology, each station can transmit and receive.

In a mono-static configuration, a station operates thus: transmit/pause/receive.

In a basic bi-static configuration as illustrate above, a transmitter operates continuously while multiple receivers tracks the target as it reflects. In a multiple transmitters/receivers set up, it is called multi-static, but the foundation is still bi-static. Mathematically, it is the bi-static triangle.

https://link.springer.com/chapter/10.1007/978-3-642-21697-8_56
The solution to the bistatic triangle for target range from the receiver requires calculating the azimuth of the direct path pulse,...

In theory, the bi-static radar is the greatest threat to 'stealth'. But there are technical challenges that STILL prevents the idea from becoming operationally readied.

One of many problems is synchronization. The receivers must know the transmitting signal and the more it knows, everything from amplitude to freq to pulse characterization, the better.

Another problem is in the signal source(s), which in this case, can be anything from TV to radio to cosmic background radiation: electromagnetic emissions in the atmosphere. The problem is TACTICAL.

What if an airstrike takes out the city's electrical generation stations? Now there are huge radar gaps in this multi-static system. The B-2 win. :enjoy:

Maybe the jets were using radar reflectors to remain visible because of the airshow
