Line Spectrum Detection Algorithm of Single Vector Sensor Based on Singular Value Difference

open access: yesApplied Sciences
The line spectrum of ship-radiated noise can be used in passive sonar to detect ship targets; however, it is affected by ocean noise and the Doppler effect, which has a negative effect on target detection. In the paper, the multi-channel data of a single

The Doppler effect and similar triangles

open access: yesResults in Physics, 2019
The Euclidean version of Doppler effect will be explained using the properties of similar triangles. These properties will serve to explain the relationship between frequencies of propagated wavefronts, number of wavefronts and the time of emitting and ...
