analytic derivation的意思|示意

The difficulty in the derivation of bistatic SAR imaging algorithms lies in the bistatic point target reference spectrum, particularly in the analytic forms.

双基SAR成像的主要难点在于解析的点目标二维频谱的求取。

Further, by double FOURIER series expansion and intricate derivation, strict output analytic solution is acquired.

针对模型，通过双fourier级数展开和繁琐的数学推导，求得了输出电压的严格解析表达式。
