You should stick to Rafale fantasy and refrain from commenting on topics that are beyond your repertoire. There were no multistatic radar in operation anywhere near the F117 shootdown.
what do mean by hang the target
? Multistatic arrangement is fixed, requires large compute resources and are susceptible to deception
* and is significantly degraded when even one node in the network is compromised. It is useful for protecting fixed strategic targets e.g. military base.
*It is assumed that since the location of the receiver(s) is not known in a multistatic arrangement the system is impossible to jam. While this is true, the system is vulnerable to deception by insertion of false targets through the independent manipulation of the pilot and carrier signal.
A large complex arrangement requires a pilot signal to synchronize the various nodes in the network. Manipulating the pilot and the carrier (information) bearing signal allows the intruder to deceive the system by inserting false targets (ghosts). Don't forget in a multistatic arrangement the transmitter and the missile battery is still vulnerable to a physical attack. The location of the passive receiver is unknowable.
All US LO platforms have an antenna farm embedded on its skin and so while in flight it detects all emitters, combines the data from other allied airborne elements and dynamically builds a 4D picture of the in theatre threat in real-time. The flight can then circumvent detection by flying along the edges of the hostile system or attack (physical or electronic) and degrade the system.
The F117 Nighthawk incident was a combination of operational complacency and a patient and clever enemy who studied F117 operational routine and through observation of US airbases knew precisely when the aircraft would fly overhead for them to take a unguided shot. The US lost one in 38000 sorties, if LO and the F-117 was vulnerable the Serbs would have shot down many US aircraft - they shot down two, one F16 and one F117.
