Nešto mi se muva po glavi, od pričanja sa radaristom. Iako helikopter lebdi (ne miče se) radar ga otkriva zbog rotora, koji se okreče, te ga tako i prepoznaje kao vazdušni cilj.

Има нешто истинито, што ти се мува по (или у) глави.
Старије верзије радара, које су радилиле, искључиво пулсно-доплеровом режиму, вероватно нису могле да детектују непокретни циљ.
Међутим, ови са ове адресе:
http://en.wikipedia.org/wiki/GIRAFFE_Radarкажу:
"
GIRAFFE AMB This newest member of the family, providing multi-beam 3-Dimensional air coverage at 5.4 to 5.9 GHz with instrumented ranges of 30 km (19 mi), 60 km (37 mi) and 100 km (62 mi), the altitude coverage is extended from ground-level to 20,000 metres (66,000 ft) with 70-degree elevation coverage. Data rate is 1-scan per-second. Its maintained pulse density suppresses high cluttering in adverse weather conditions. Ultra-low antenna side-lobes combined with
pulse-to-pulse and
burst-to-burst frequency agility provides some resistance to jamming.
As in previous Giraffe radars automatic hovering helicopter detection is provided as is an artillery and mortar locating function, allowing the radar to detect incoming rounds and give 20 seconds or more of warning before impact. Giraffe AMB is the principal sensor of the Swedish RBS 23 BAMSE air defense missile system but is available for many other applications. A skilled crew can deploy the radar in around 10 minutes and recover it in around 6 minutes."
Колико "транслатор" помаже: ово би требало да буде решење за лебдеће хеликоптере, па чак и гранате-мине. Ови који се боље разумеју у тај "енгелески" могу прецизније да нам растумаче.
