The linear sweep method can be fooled by introducing garbage data immediately after an unconditional jump instruction. 通过在一条无条件跳转指令之后立即插入无用数据，能够欺骗线性扫描方法。
Thus, each of the scanning methods is completely reversible and works equally well in reception of energy as in transmission. 这样，各种扫描方法都是完全可逆的，并且在接收方面与发射能量是等效的。
