基于散射系数Rayleigh模型的校正因子估计
CALIBRATION FACTOR ESTIMATION BASED ON RAYLEIGH MODEL OF SCATTERING COEFFICIENT
摘要
Abstract
The calibration factors of synthetic aperture radar ( SAR) images are generally obtained by estimation of radar system parameters. Based on the Rayleigh model of scattering coefficient, a simple but efficient estimator is proposed to estimate the calibration factors. Taking expectation and variance on the linear form of calibration equation, and describing scattering coefficient as the Rayleigh model, the estimator with analytical expressions is derived for the linear receiver and the square-law receiver. Monte Carlo simulations demonstrate that the proposed estimator on the basis of Rayleigh model of scattering coefficient has high estimation accuracy.关键词
