A hf radio architecture exists that will significantly aid the navy performing major upgrades to their overall communications network and reduce the number of different type hf radios presently deployed. the architecture is based on the application of i and q bandwidth sampling, digital… More

This proposal describes the start of an effort to develop an adaptive jammer system. there are several technical problems to solve before the adaptive jammer can be developed. one difficulty encountered with the adaptive jammer system can be solved by designing the exciter to provide the required… More

The dirad team has identified a digitally implemented receiver architecture that provides unique performance capabilities presently unattainable in conventional analog receiver implementations; bandpass filter characteristics, wideband agc operation, noise reduction/ adaptability, multiple… More

This proposal describes an effort to design an expendable jammer which can direct its energy in a direction which has either been pre-programmed into it or has been commanded over some form of control link. using cheap, simple, non-mechanical direction finding sensors, it is possible for the jammer… More
