scope of a variable
variable range

Law of the iterated logarithm for nonstationary negatively associated random fields
随机变量域的重对数律
A chirp scaling algorithm for airborne bistatic sar is proposed , which is suitable for the flight configuration that transmitter and receiver follow parallel path with equal velocity in broadside looking mode . airborne bistatic sar echoed signal model of this particular flightpaths is derived . the model is converted into the range doppler space and is mapped from double range variables to single range variable domain
本文建立了这种特殊飞行模式下双基地sar的回波信号模型,推导了它在距离多普勒域的表达式,解决了信号模型从双距离变量域向单距离变量域转化的问题,并推导了cs因子的线性近似表达式,分析了算法中各种近似造成的误差。
