A new restoration algorithm based on double loops and alternant iterations is proposed to restore the object image effectively from a few frames of turbulence-degraded images. Based on the double loops, the iterative relations for estimating the turbulent point spread function PSF and object image a...

A new long term integration algorithm is proposed for high-dynamic targets, which can resolve the problems of spectrum spread, frequency walk and pseudorandom noise (PRN) code phase curvature caused by the motion of targets. This algorithm first applies a keystone transform based improved discrete p...

A systematic elaboration is given on atomic and molecular theory problems encounteredin dealing with space science and engineering. Three sections are presented in the paper on calculations for gas thermodynamic and transfer properties, characteristics of the optical radiation fromthe reentry bodies...

An ultrashort 10-GHz pulse generation scheme was successfully demonstrated using a bulk material InGaAsP electroabsorption modulator to generate the seed pulse. A self-phase modulation-based reshaper was used after the adiabatic soliton compression in a comb-like dispersion profiled fiber. Experimen...

To estimate the angle of arrivals (AOA) of wideband chirp sources, a new time-frequency algorithm is proposed. In this method, virtual sensors are constructed based on the fact that the steering vectors of wideband chirp signals are linear and vary with time. And the randon Wignersville distribution...
