The mechanism of 3-D SAR with fixed transmitter is discussed in this paper.
The schematic diagram of 3-D SAR with fixed transmitter is illustrated in Figure 3, which consists mainly of a transmitter, receiver, motion platform and synchronous module.
According to the scattering theory, the mechanism of 3-D SAR with fixed transmitter can be explained via two stages:
In the viewpoint of scattering center model, 3-D SAR with fixed transmitter works at bistatic mode, and the non-backscattering problem should be considered during modeling.
In free space, the Maxwell equations can be solved as the Stratton-Chu integral equation, which is convenient to analyzing the mechanism of 3-D SAR with fixed transmitter.
The nature of 3-D SAR with fixed transmitter is to recover the electric/magnetic current densities using the measured voltage data.
EXPLANATION OF 3-D SAR IMAGE WITH FIXED TRANSMITTER
Equation (15) indicates that the imaging results of 3-D SAR with fixed transmitter are the estimations of the electric current density for perfect conductor.
Within that area, anyone who wanted to install a fixed transmitter had to demonstrate that their signals would not interfere with astronomers' observations.
The case of two moving receivers locating a fixed transmitter is shown in Figure 4.
Civilian cell phone networks operate wirelessly, but they are dependent on fixed transmitters, often atop of buildings or high elevations, which receive the transmissions from a cell phone and transmit these to another tower until they reach their intended destination.
Firstly, as the radios build and maintain the network there is no need to move large numbers of fixed transmitters into theatre to established a fixed network in a similar fashion to cell phone communications; this reduces time to establish the network, and the accompanying cost in terms of financial and human capital.
