The design principle of radar intermediate-frequency echo is introduced; different kinds of expression of echo signals are deduced, and 4 categories of wave of targetcrosssection are modeled.
The panel crosssection is analyzed in the model, and the feasible zone of all crosssection rotating angle is located, and a group of target function is proposed as optimized object.
该模型分析了冲压件截面形状，确定所有截面转角的公共可行域，并建立一组目标函数作为优化对象。
