A new method of target detection for polarimetric radar in the presence of strong active jamming is proposed. Based on analysis of the polarization characterizations of the signals received by polarimetric radar, the target detection is achieved through testing on the polarization information. Comparing with the traditional method of target detection made in time-frequency domain, the detection performance...
This paper explores a unique calibration method for polarimetric radar without requiring any calibration targets. The error of the polarimetric scattering matrix measurement is modeled as antenna distortion matrices and channel distortion matrices. These distortion matrices can be determined using a signal generator in anechoic chamber. The performance of the calibration method is analyzed by simulation...
This paper explores the simultaneous estimation method of the AOA and the polarization of the signals. Based on two differently polarized antennas, the simultaneous estimation is achieved with consideration of the cross-polar and co-polar patterns of the antennas. The performance of the method is analyzed. The validity is testified by the experiment of P-band radar system.
A new far-field measurement method of antenna is studied in this paper. The received signal model of antenna's beam scanning the calibrator target has been built and the measurement method is considered. The full analysis formula and practical procedure was given. The validity of research work was demonstrated by processing the observational data and simulation. This can greatly reduce the development...
The band characteristics of the signal-to-interference-and-noise-ratio polarization filter to one signal in the presence of single noncoherent, purely polarized interference are investigated. The formulae of the filter band width on the polarization tracks and in the whole polarization region are presented. The quantitative description and the characteristic curves of the band scale are also given
