Polarization scattering matrix Completely describes the electromagnetic scattering properties of radar targets. Accurate and effective measurement of radar target polarization scattering matrix is a prerequisite for many studies in the field polarization. The more common methods of measuring the polarization scattering matrix has a little Shortcoming. The more typical is the need to match a pair of zero polarization orthogonal polarization antenna.but this case is ideal, Because in practice between the orthogonal polarization antenna there are some inevitable interference,Therefore, research measurement of polarization scattering matrix of objectives is necessary.The paper combine radar polarization theory and antenna theory, on the basis of echo polarization information,to discuss the radar echo simulation, polarization synthesis and antenna polarization characteristics of the airspace.And next,the paper discuss a measurement method of polarization scattering matrix based on the antenna polarization characteristics of the airspace,and verify its effectiveness. The main thesis is as follows:1. The simulation of radar echo plays an important pole in the phase of system design,manufacture and debugging.this paper analyzes the producing of beam control code and target loci.When the beam encourter the target,the information of target state and characteristic is released. The modularion course of these information is given from the generation of radar signal to receive,and the computer simulation is presented.It provides the foundation of radar echo simulation.2. Discuss the polarization synthesis,and the use of polarization synthesis techniques have get several typical and conventional target polarization response and conduct analysis.It provides a theoretical analysis for the study of scattering echo characteristics of the complex targets.3. Analyzes the polarization characteristics of the airspace of the rectangular aperture and circular aperture antenna. On this basis, two methods of objective polarization scattering matrix measurement are discussed in detail Analyzes the principle and performance of the algorithm,and does a lot of computer simulation.finally,I analyzes the Algorithm weaknesses and Related Simulation...
