High-Fidelity, Delta-Sigma Waveform Generator (9695)

Q-DOT proposes to develop a High-Fidelity, Delta-Sigma Waveform Generator (DS WG) for high-fidelity specific emitter identification (SEI) signal simulators. This approach can be used to generate precision, pulsed waveforms mimicking unintentional modulation on pulse (UMOP). The UMOP can be any combination of amplitude, frequency, or phase. A single DS WG can generate diverse radar waveforms (e.g., linear FM, pulsed CW, PRN) and spectrally efficient communications waveforms (e.g., multi-h CPM and SOQPSK), all under software control. Its superior signal quality (100 dB SFDR, -155 dBc/Hz noise floor) is advantageous for local oscillators as well. In Phase I the capabilities of DS WG will be demonstrated. Prototype DS WG modules will be built, demonstrated, and delivered during Phase II.
