Shoemaker-Levy 9 Impact Modeling: I. High-Resolution 3D Bolides
, 2006 We have run high-resolution, three-dimensional, hydrodynamic simulations of the impact of comet Shoemaker-Levy 9 into the atmosphere of Jupiter. We find that the energy deposition profile is largely similar to the previous two-dimensional calculations of

Sparse Representation Denoising for Radar High Resolution Range Profiling [PDF]
International Journal of Antennas and Propagation, 2014 Radar high resolution range profile has attracted considerable attention in radar automatic target recognition. In practice, radar return is usually contaminated by noise, which results in profile distortion and recognition performance degradation. To deal with this problem, in this paper, a novel denoising method based on sparse representation is ...

The rotational velocity of the sdOB primary of the eclipsing binary system LB 3459 (AA Dor)
, 2003 We present an analysis of the rotational velocity of the primary of LB 3459 based on 107 new high-resolution and high-S/N ESO VLT UVES spectra. 105 of them cover a complete orbital period (0.26 d) of this binary system.

Time-Domain Scattering Characteristics and Jamming Effectiveness in Corner Reflectors
IEEE Access, 2021 The outboard corner reflectors are widely used as a countermeasure to radar tracking and detection. Therefore, it is essential to determine the composite time-domain scattering characteristics of the corner reflector and ship against the sea background ...

Linear/circular spectropolarimetry of diffuse interstellar bands
, 2011 Context. The identification of the carriers of diffuse interstellar bands (DIBs) remains one of the long-standing mysteries in astronomy. The detection of a polarisation signal in a DIB profile can be used to distinguish between a dust or gas-phase ...

A New MCMC Sampling Based Segment Model for Radar Target Recognition [PDF]
, 2015 One of the main tools in radar target recognition is high resolution range profile (HRRP). However, it is very sensitive to the aspect angle. One solution to this problem is to assume the consecutive samples of HRRP identically independently ...

High Range Resolution Profile Construction Exploiting Modified Fractional Fourier Transformation [PDF]
Mathematical Problems in Engineering, 2015 This paper addresses the discrimination of closely spaced high speed group targets with radar transmitting linear frequency modulation (LFM) pulses. The high speed target motion leads to range migration and target dispersion and thereby the discriminating capability of the high range resolution profile (HRRP) deteriorating significantly.
