In this paper, a bistatic SAR echopsilas mathematical expression with time errors is given, and the time errors was analysed. Three types of time errors were considered. We analysed the different effects on imaging of bistatic SAR under the condition of different time errors in the system. The analytical result is proved by simulation results, it can be used for reference in bistatic SAR system design.
In wireless navigation system worked on medium-short wave, skywave interference is a serious problem which influences the work region and orientation precision. Based on the model analysis of skywave interference, the method of using multi-user detection technique to eliminate sky wave interference is proposed. Estimate and rebuild the strong skywave interference, remove it from received signals,...
This brief presents a detailed time-domain and frequency-domain analysis of a direct RF sampling mixer. Design considerations such as incomplete charge sharing and large signal nonlinearity are addressed. An accurate frequency-domain transfer function is derived. Estimation of noise figure is given. The analysis applies to the design of sub-sampling mixers that have become important for software-defined...
