Noise radar technology: Pseudorandom waveforms and their information rate [PDF]
2014 15th International Radar Symposium (IRS), 2014 The well-known LPI (Low Probability of Intercept) and antispoofing capabilities of some radar waveforms as well some other desirable feature such as a low sidelobes level of their autocorrelation function can be enhanced by “tailored” pseudo-random sequences, whose phase is made up by a deterministic part plus a variable random term.

Optics Express, 2022 In this work, a high signal-noise ratio (SNR) dynamic biasing InGaAs/InAlAs avalanche photodiode (APD) is demonstrated experimentally and first applied in a laser radar system. Combining with the dynamic biasing technology, the APDs are operated in an unexploited voltage range between linear mode and Geiger mode, which, in this work, is defined as a ...
