摘要

在星载双基地SAR、机载双基地SAR已有成果的基础上

分析了星机双基地SAR中时间同步误差的影响.利用已有文献提出的一种时间同步误差模型

针对星机双基地SAR中误差的影响进行了定量分析

并进行了仿真验证.结果表明:按目前振荡源的实际频率准确度和稳定度

脉冲重复频率抖动的影响可忽略

线性时间同步误差是影响成像指标的主要误差源.最后

推导了实施同步方案后系统允许的"剩余同步误差"的量化指标要求.

Abstract

The impact of time synchronization errors on the spaceborne/airborne hybrid bistatic SAR (SA-BSAR) is analyzed on the basis of several existing results applied to the spaceborne bistatic SAR or the airborne bistatic SAR.Quantitative error analysis

uniquely for the SA-BSAR system

is performed using an existing model for time synchronization errors.Several simulation experiments were carried out and the results indicate that in the SA-BSAR system

taking the practical accuracy and stability of the current oscillator into consideration

the impact of the pulse repetition frequency (PRF) jitter is trivial and the linear time synchronization error is proved to be the major error source.At last

the requirement on the residual errors is derived.
