Abstract
A Link 16 compliance monitoring system, and Link 16 compliance monitoring semiconductor integrated circuit, for LLD monitoring, frequency bin monitoring, and pulse width monitoring comprising an LLD monitoring subsystem, a frequency bin monitoring subsystem, and a pulse width monitoring subsystem, all sharing a frontend subsystem that performs A/D conversion of the inputted Link 16 transmission RF signal and that reduces overhead in digital signal processing by digitally multiplying the Link 16 transmission RF signal by a 1060 MHz complex sine wave waveform and then decimating the result.
Claims19
A Link 16 compliance monitoring system comprising:
- an analog-digital (A/D) convertor configured to receive, and perform A/D conversion on, a Link 16 transmission radio frequency (RF) signal to produce a series of digital voltage samples representing a waveform of the inputted Link 16 transmission RF signal;
- a digital 1060 MHz oscillator configured to produce a series of digital voltage samples representing a 1060 MHz waveform and
- a first digital multiplier, in operative communication with the A/D convertor and the digital 1060 MHz oscillator, configured to 10 digitally multiply digital voltage samples from the A/D convertor and digital voltage samples from the digital 1060 MHz oscillator to 12 produce a series of digital voltage samples.
