The Doppler effect induced by earthquakes: A case study of the Wenchuan MS8.0 earthquake
Seismologists have found that the first arrival frequencies of P waves at different seismic stations have different widths, that is, different periods or frequencies, and they think that this phenomenon can be used to identify whether a Doppler effect is

Main-lobe jamming cancellation for multi-static radar by joint range-Doppler processing
It is well-known that the noise jamming impedes the mission effectiveness of radar systems. It raises the level of the background and swamps out target returns.

Moving Target Simulation of Multi-Band Radar Based on Doppler Frequency Signal Generation Technology [PDF]
This paper proposes a corner reflector and Luneburg ball reflector group. The omnidirectional radar cross-sectional (RCS) distribution characteristics of a fighter are simulated using the sharp and smooth RCS distribution features of the corner and the ...

Analysis of phase noise influence on micro-Doppler feature extraction of vibrating target
It is generally considered that increasing the carrier frequency of radar is an important way to improve the precision of micro-motion measurement. However, the increase of the radar frequency may raise the phase noise intensity of the radar transmitting
