COMPENSATION OF THE IONOSPHERIC EFFECTS ON SAR INTERFEROGRAM BASED ON RANGE SPLIT-SPECTRUM AND AZIMUTH OFFSET METHODS – A CASE STUDY OF YUSHU EARTHQUAKE
InSAR Ionospheric effects Range split-spectrum Azimuth offset Ionosphere correction Yushu earthquake
2018/5/14
InSAR technique can measure the surface deformation with the accuracy of centimeter-level or even millimeter and therefore has been widely used in the deformation monitoring associated with earthquake...
Comparison of the reference mark azimuth determination methods
Geodetic (ellipsoidal) azimuth Astronomic azimuth Repeat station Reference mark GNSS CROPOS
2015/8/26
The knowledge of the azimuth of the reference mark is of crucial importance in the determination of the declination which is defined as the ellipsoidal (geodetic) azimuth of the geomagnetic meridian. ...
Tight focusing of a double-ring-shaped, azimuth ally polarize d beam
Tight focusing a double-ring-shaped azimuth ally polarize d beam
2013/7/3
We study the focusing properties of a double-ring-shaped azimuthally polarized beam through an annular high NA objective lens. It is shown that a subwavelength focal hole (～ 0:5λ) with a quite long de...
We present measurements of both $p_t$-integral and $p_t$-differential azimuth quadrupole components of two-particle correlations on azimuth ($\phi$) and pseudorapidity ($\eta$) for unidentified hadron...
Optimal thrust allocation method under the constraints on azimuth thrusters' angles using piecewise linear interpolation
azimuth thrusters' piecewise linear
2009/3/27
Thrust allocation is one of the most important problems for the motion control of a ship with rotatable azimuth thrusters.
On thrust allocation methods under the constraints on azimuth thrusters' angles
DPS azimuth thrusters
2009/3/27
In a ship DPS equipped with azimuth thrusters, desired forces and moment are realized by means of thrust allocation or control allocation (CA) of determining magnitudes of thrusts and directions of th...
