What feature does the SINCGARS use to reduce the threat of jamming and minimize the use of direction-finding equipment to establish your location?
SINCGARS radio's frequency hopping covering the 30 to 87.975 MHz band in 2,320 channels. Older direction-finding equipment that use a conventional receiver channel will have trouble direction-finding a frequency hopping radio, but direction-finders sets that use what amounts to a spectrum analyzer can DF a frequency hopping radio, and probably can de-interleave a number of them, so the anti direction-finding part of the reason for frequency hopping is not too strong. Note that SINCGARS uses about 100 hops per second, which is considered a slow hop. It is not a direct sequence spread spectrum system like is used by GPS. Once a frequency hopping radio has been located by direction-finding equipment then it's possible to jam it. Not by knowing the hop sequence, but by listening for each new transmission (like using a very fast spectrum analyzer) and then jamming that transmission, then the next, and so on. So the advantage of Frequency Hopping against a sophisticated enemy has a short life.
