The maximum fracture width and azimuth are not related.
However, though the smart antennas can adjust the elevation, beam width, and azimuth angle, the changing is very slow [12].
Indeed, in that case, there are many new factors that would be necessary to be taken into account such as the effects of site latitude, planting density, row width and azimuth.
The following a priori information: road data base (routes in two directions) [16], vehicle sizes for passenger cars and trucks, road parameters (number of lanes, lane width) and solar azimuth and zenith angles is used in the proposed method.
The location of the Mogi point source and the locations, sizes (length and width), and orientations (azimuth and dip) of the two open cracks in 2013 were assumed to be the same as in the deformation source model for the 2001 swarm activity by Daita et al. (2009).
The designed width, thickness, wedge angle, and azimuth angle of the wedge were 50.0 mm, 10.0 mm, 0.28°, and 22.5°, respectively.
After these processes, we studied morphological characteristics of horizontal structures, i.e., length, width, elongation azimuth, and their migration velocities, read by eye using 5 min snapshots like those shown in Fig. 3.
Based on the road network database, such as road class, road location, road width and maximum velocity, the azimuth displacement map and the interferometric phase map of moving targets around the roads can be computed analytically pixel by pixel as stated in [4].
In the simulation, the system parameters are listed in the middle column of Table 1 and beam width in azimuth dimension is set to be 0.059 rad.
Using the SAR simulation parameters in Table 1, we generate the raw data of these three targets when SNR is 5 dB and beam width in azimuth dimension is 0.0785 rad.
At the transmitter side, a vertically polarized horn antenna with a 72° azimuth plane beam width and a gain of 8 dBi was used.
