ModelEvaluatTargetLocatPrec
以地基分布式有源雷达组网系统为讨论对象,在具体分析了4种系统定位误差的相互关系的基础上,给出了一种
基于ECEF转换法的系统目标综合定位精度评估模型,并利用典型的雷达参数,对2D与3D混合的雷达组网系统的实际目标
综合定位精度进行了仿真和对比分析,得到了一些对雷达组网系统的实际部署优化处理有参考价值的结论。
(The land-based distributed active radar network system is taken as discussion object.On the
basis of the concrete analysis of the interrelation among four sorts of locating errors, a model of evaluating
the integrated system locating precision is put forward. By using the typical radar parameters, the
simulation a of the actual integrated locating precision of 2D/3D hybrid radar network systems are done.
Conclusions that are helpful for optimization of radar network disposition are obtained.

sun_position
一个相当好用的matlab函数，由美国国家可再生能源实验室科研人员设计，可以计算太阳的直射维度和方位角。只要输入时间、观测地点即可。 (This algorithm is based on numerical approximation of the exact equations.
The authors of the original paper state that this algorithm should be
precise at+/- 0.0003 degrees. I have compared it to NOAA solar table
(http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and to USNO solar
table (http://aa.usno.navy.mil/data/docs/AltAz.html) and found very good
correspondance (up to the precision of those tables), except for large
zenith angle, where the refraction by the atmosphere is significant
(difference of about 1 degree). Note that in this code the correction
for refraction in the atmosphere as been implemented for a temperature
of 10C (283 kelvins) and a pressure of 1010 mbar. See the subfunction
un_topocentric_zenith_angle_calculation� for a possible modification
to explicitely model the effect of temperature and pressure as describe
in Reda & Andreas (2003). )
