True polar wander driven by late-stage volcanism and the distribution of paleopolar deposits on Mars [PDF]
, 2009 The areal centroids of the youngest polar deposits on Mars are offset from those of adjacent paleopolar deposits by 5-10 degrees. We test the hypothesis that the offset is the result of true polar wander (TPW), the motion of the solid surface with ...

Prospects of FMCW-based frequency diverse array radar
The Journal of Engineering, 2019 The linear frequency modulated (LFM) frequency modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is investigated in detail. The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as

Dechirp‐receiving radar target detection based on generalized Radon‐Fourier transform
IET Radar, Sonar & Navigation, 2021 The dechirp‐receiving radar measures range by the frequency difference between the target echo and the reference signal. It can operate at a low sampling frequency while transmitting a wideband signal, which simplifies the radar hardware.
