Advanced Direct Digital Exciter for Radar (ADDER)

In the Phase II effort, CEI will develop an Advanced Direct Digital Exciter for Radar (ADDER) targeted for the AN/SPS 49A(V) (SPS-49) search radar as part of the SPS-49 technical refresh with relevance to other military and commercial applications (e.g. exciter, Software Defined Radio (SDR)). ADDER will directly replace the multi-step Intermediate Frequency (IF) analog conversion with direct-digital-to-Radio Frequency (RF) conversion — no superheterodyne mixing stages required. The benefit of this conversion includes reduced noise, instability, part count, Total Operation Cost (TOC) and increased Digital Signal Processing (DSP)/frequency diversity flexibility. CEI will utilize decades of expertise in EW, radar, Digital-to-Analog Converter (DAC) board design, RF, DSP and mechanical ruggedization to successfully develop, package, integrate, test and commercialize this state-of-the-art technology.
