Consistency-based Air Target Height Estimation and Location in Distributed Space-based Radar Network
Leida xuebao, 2023 When single space-based radar tracks and detects air targets, problems such as missing pitch angle information and nonlinear measurement lead to large target height estimation errors. Multi-space-based radar networking can solve this problem.

Discrete Spectrum cover Signal Waveform Design and Generation Method
Leida xuebao, 2023 Radio Frequency-screen is one of the earliest radar active antijamming measures. It achieves antijamming by transmitting cover pulses of different frequencies before the radar pulse signal to induce enemy jammers.

Wavelet Transform-Based Signal Denoising in Low-Field NMR
Chinese Journal of Magnetic Resonance, 2018 Low-field NMR often uses permanent magnet. The signals obtained contain high level of white Gaussian noises, and have low signal-to-noise ratio (SNR). In recent years, many denoising methods have been proposed for low-field NMR measurements.

Increased sensitivity in electron–nuclear double resonance spectroscopy with chirped radiofrequency pulses [PDF]
Magnetic ResonanceElectron–nuclear double resonance (ENDOR) spectroscopy is an EPR technique to detect the nuclear frequency spectra of hyperfine coupled nuclei close to paramagnetic centers, which have interactions that are not resolved in continuous wave EPR spectra and
