Study on the Effective Region of Active Decoy Jamming to SAR Based on Time-delay Doppler-shift Method

open access: yesLeida xuebao, 2013
The active decoy jamming to SAR based on the Time-Delay Doppler-Shift (TDDS) method takes effect in certain region. Proper utilization of jamming ensuring decoy quality is based on the study of the effective region. After the mathematical analysis of the

Photoionization Time Delays [PDF]

open access: yes, 2015
The material presented in this chapter is based on important advances realized in “attophysics” which make feasible to follow the motion of electrons in atoms and molecules with attosecond-level time resolution. In this context, time-delays have been recently determined in the process of photoionization by extreme-ultra-violet (XUV) pulses and the ...

Delay regulated explosive synchronization in multiplex networks

open access: yesNew Journal of Physics, 2019
It is known that explosive synchronization (ES) in an isolated network of Kuramoto oscillators with inertia is significantly enhanced by the presence of time delay. Here we show that time delay in one layer of the multiplex network governs the transition
