The waveform of the time-varying magnetic field can be reconstructed by combining the use of quantum sensing technology and orthogonal functions, such as Walsh and Haar wavelet functions, as the control sequences of qubits. However, the piecewise-con

The Fermi bubbles and the eROSITA bubbles around the Milky Way Galaxy are speculated to be the aftermaths of past jet eruptions from a supermassive black hole in the galactic center. In this work, a 2.5D axisymmetric relativistic magnetohydrodynamic

A complete framework of predicting the attributes of sea clutter under different operational conditions, specified by wind speed, wind direction, grazing angle, and polarization, is proposed for the first time. This framework is composed of empirical

A novel FH-LFM-FD-MIMO radar system is proposed to detect and localize true targets while suppressing false-target jamming signals. Linear frequency modulated (LFM) pulses are transmitted by a transmit array, with the carrier frequencies optimized to

Chaotic maps have been widely applied on image encryption for their complexity and sensitivity to key variation. In this work, we propose second-order chaotic maps with optimized random coefficients to generate chaotic sequences for image encryption.

An inverse synthetic aperture radar (ISAR) technique is proposed to acquire high-resolution steady images of high-speed aerial target with radar installed on a moving vessel. The phase changes due to target motion and attitude perturbation of the ves

A war game between two matched fleets of equal size and capability is designed and simulated in this work. Each fleet is composed of a carrier vessel (CV), a guided missile cruiser (CG), and two guided-missile destroyers (DDGs). Each vessel is equipp

Duo airborne synthetic aperture radars in the $X$-band are proposed to acquire images of a flying helicopter. The backscattered signals manifest entangled features attributed to the compound linear motion of fuselage and spin motion of rotors. A two-
