| The polarization information is now becoming more and more important as the polarization information disposal technique of radar is developed and more and more radars with polarization information disposal capability is appeared. Antenna is an important part of radar, whose polarization character of time domain, frequency domain and special domain has a direct correlation with radar information disposal precision. So the analysis of antenna spacial polarization capability and discussing the spacial polarization character of antenna design has an important meaning for polarization radar application and new type of polarization information disposal, provides the theoretics basic for spacial polarization information disposal. This article analysed the spacial polarization character of all types of antenna, designed a new type of spacial various polarization antenna, and discussed the measure application in polarized scatter matrix, acquired some production as follows:1. Analysing the typical type of antennas in the ideal situation, discussing their spacial various polarization character, the result indicated that the antenna had an obviously spacial polarization change, showing the rule of the antenna polarization change.2. Designing the spacial various polarization antenna which got the many polarization state including horizontal and vertical polarization in the airspace.3. Based on the discussing of antenna spacial polarization character token, Analysing the spacial polarization character of an antenna, providing the theory for the antenna spacial instantaneous polarization.4. Bringing forward two kinds of fixed target polarization scatter matrix measurement, fourierism method and integral method, indicating the new thought for the polarization information disposal technique. |
