Most radio signals can be described as a form of sinusoidal carrier modulation. These signals have the property that when observed over a sufficiently short period of time, the waveform is approximately sinusoidal, exhibiting constant magnitude, frequency, and phase. When coherently digitized with sufficiently high sample rate, it is possible to discern this sinusoid. The associated signal can be represented as a sinusoid with time-varying frequency, magnitude, and phase. These parameters can…

Coherent Time-Domain Canceling of Interference for Radio Astronomy

Radio astronomy is vulnerable to interference from a variety of anthropogenic sources. Among the many strategies for mitigation of this interference is coherent time-domain canceling (CTC), which

RFI suppression for ultra wideband radar

TLDR
An estimate-and-subtract algorithm is presented for the real-time digital suppression of radio frequency interference in ultrawideband (UWB) synthetic aperture radar (SAR) systems used for foliage- and ground-penetrating imaging, thereby reducing target energy loss and sidelobe levels in SAR imagery.

MITIGATION OF RADAR INTERFERENCE IN L-BAND RADIO ASTRONOMY

The 1215-1400 MHz band is important for spectroscopy of H I at high redshift, pulsar work, and SETI. Observations at these frequencies are complicated by pulsed interference from ground-based
