Polarization cancellation is an effective method to improve the radar target detection performance under the main lobe interference environment. Interference suppression ratio is widely used to assessment polarization filter performance. However, the radar target detection performance is determined by the Signal Interference plus Noise Ratio (SINR). It is important to analyze the polarization filter's...
The polarisation ratio (PR) of an electromagnetic wave can provide information on the scattering from natural targets or on the emission from radio sources. In this study, a dual-polarisation radar operating at simultaneous reception mode is taken into account. Statistical properties of the PR of the radar signals on the basis of complex Gaussian models with zero and non-zero means are derived, respectively...
We consider radar systems with simultaneous dual-polarization reception capability. A new polarized radar model that includes the influence of the environmental disturbance factor on the received signal is established. It is demonstrated that the degree of polarization of the received signal is related to not only the signal-to-noise ratio but also to the electromagnetic waves' polarization state...
In this study, the radar returns from a target with deterministic polarization in clutter environments illuminated by fully polarized waves are taken into account. Statistical properties of the polarization ratio for radar returns are obtained on the assumption of complex Gaussian distributions with non-zero means. Probability density functions (PDFs) of the amplitude ratio and the phase difference...
