The invention belongs to the technical field of radars, and discloses a
radar networking anti-interference method based on a
digital array radar software definition multifunctional
digital radio frequency technology. Various working
modes of conventional
radar narrowband and
broadband detection, multi-
station cooperative detection and anti-interference, external
radiation source cooperative detection, single-
station / double-
station MIMO detection,
channelized external
electromagnetic environment cognitive reconnaissance, cooperative interference, detection and
drying integration, multi-platform communication and the like can be realized at the same time. High-isolation
signal frequency diversity is realized by using a wide-
narrow band signal receiving and transmitting channelization technology, effective coding isolation diversity is realized by using coding pulses, and multifunctional
signal time diversity is realized based on partial function
time division multiplexing. According to the method, a set of
broadband hardware
system with composite functions is reused, electronic functions required by a radar networking
system are achieved through different
software, the purpose of
software definition functions is achieved, and meanwhile the anti-interference capacity of the networking
system is enhanced.
