Design and Processing of a Novel Chaos-Based Stepped Frequency Synthesized Wideband Radar Signal
Sensors, 2018 The linear stepped frequency and linear frequency shift keying (FSK) signal has been widely used in radar systems. However, such linear modulation signals suffer from the range–Doppler coupling that degrades radar multi-target resolution.

A bimodal correlation between host star chromospheric emission and the surface gravity of hot Jupiters [PDF]
, 2015 The chromospheric activity index logR'HK of stars hosting transiting hot Jupiters appears to be correlated with the planets' surface gravity. One of the possible explanations is based on the presence of condensations of planetary evaporated material ...
