Gaussian Noise Generators are common in various applications of Electronic Countermeasures and Low Probability of Intercept radar. It can be applied to military applications, law enforcement and commercial segments. The key requirement for such a generator is the ability to operate in wide spectral band. The main driver for this requirement is the ever increasing radars bandwidth to achieve high radar resolution.In addition to wideband capabilities, it is important to have a fine control over the suppressed and unsuppressed spectral frequencies. The countermeasures must allow friendly system to continue to operate, while suppressing the adversary systems. Moreover, due to limited transmit power envelope on analog RF power amplifier chain, it is advantageous to limit a transmission only to specific band-limited regions. The countermeasures should be able to reconfigure its settings in terms of active spectral frequencies agilely, when operational conditions or power considerations change. This paper presents proposed implementation on FPGA that achieves such key metrics.
