The Monopulse Secondary Surveillance Radar or MSSR is an improved version of the classic SSR of the 50s.
In the middle of the 70s engineers tried to avoid some standard problems of SSR. In particular Garbling and the False Replies Unsynchronized with the Interrogation Transmissions or simply FRUIT to improve "Vertical runners" detection.....

Garbling was happening when Runners are close to each other were sending very narrowly spaced replies to the SSR and its decoder was unable to detect them separately.

The FRUIT was the result of many SSRs working in the same area where the reply from a "Vertical Runner" due to the interrogation of one was also received by another SSR that has not yet sent out an interrogation for this Runner.

Both problems resulted in loss of "Vertical Runner" position producing inaccuracies.
