The new Chinese radars can be a threat to stealth.

The gallium oxide diodes can make it possible to create compact radars for stealth fighters. This system enables the creation of new shapes for stealth fighters' profiles. This allows free aerodynamic planning and the use of more accurate shapes.  But these kinds of systems. Makes it possible. To create more advanced radar systems than before. The simplest way is to install more radars on aircraft. Those radars and other sensors can observe the area around the craft. Those kinds of systems. They can search for incoming enemy missiles and aim the weapons. Into positions where they came. 

The system. It can be created by using multiple radar arrays. This means that the new jet-fighters can have radar systems. Those are like mosaics. Each of the pieces of the mosaic structure is an independently operating radar. This means that radar. This means that some of those radars can operate in passive mode. When some other radar illuminates that plane, those systems can track it. The problem with jammers is this. They must operate at the same frequency as radars. 

"By improving detection capabilities against drone swarms, the technology could strengthen air-defense networks."(Interesting Engineering)

That they must jam. So if the system sees that it’s jammed. It can shut down transmitters. And then the passive system. That is the radar receiver antenna. It can be used to track the jammer. In the same way. The radar-warning systems can have a triangular measurement system. That system can point the radar’s location with a very high accuracy. 

The mosaic-based arrays can scan an area using many radio frequencies. At the same time. Those kinds of systems can be more immune to jammers than old-fashioned radars. The radar operates as an entirety. The AI connects the data that the radar group gets. Then that AI. It can connect that data with the data flow. Which comes from other sources. Like optical sensors. Those sensors. They can be in other aircraft. Ground-based, or drones. 

Or they can operate onboard the plane. This means that those systems can get more data than ever before. And that makes those systems more intelligent and more effective than before. Those systems are based. On network-based solutions, which connect the entire battlefield. Into one entirety. The system shares data between multiple systems. 

The new radar systems use AI algorithms to analyze and sort information flow. Those new systems can detect drone swarms and then separate decoy drones from real drones. But the problem is that all drones can carry explosives. And they can all be devastating. The system. That AI can search and identify targets with new accuracy. The AI algorithms can also analyze threats with new accuracy. This thing makes the attackers and defenders deadlier than ever before.
