The invention provides an anti-
broadband interference Beidou vehicle-mounted all-in-one
machine. The anti-
broadband interference Beidou vehicle-mounted all-in-one
machine is composed of a host machineand a cable; the
host machine comprises an anti-interference
antenna array element, a receiving channel module, a power
amplifier / combiner, an anti-interference module, a transmitting filter, a
baseband signal processing board, a power source information board, a power source filter and the like; the core of the all-in-one
machine of the invention is the anti-interference module; according to theanti-interference module, a
frequency domain narrowband interference suppression and space-time adaptive
notching processing cascaded mode is adopted, namely,
frequency domain narrowband interferencesuppression is performed on intermediate-frequency signals, space-time adaptive
processing is performed on a
notching result, and therefore,
broadband interference can be suppressed. According to theanti-broadband interference Beidou vehicle-mounted all-in-one machine of the invention, anti-interference performance,
system complexity degree, reliability,
power consumption and other factors are balanced. The anti-broadband interference Beidou vehicle-mounted all-in-one machine can
resist narrow-band interference and multi-broadband interference simultaneously, perform up-conversion on interference-cancelled signals so as to obtain
radio frequency signals, and process navigation signals according to a conventional method.
