最后，建立了箔条云团干扰回波的模型。

Finally, the echo model of chaff disturbance is built.

第二种方法是使用一种有序的多波段发生器，这样可以更容易的匹配回波信号，但同时也更易受到干扰。

A second approach is to use a wide range of sequential frequencies; this is easier to match but more prone to interference.

然而，这种雷达的回波经常受到干扰而产生杂波，使信号模糊不清。

However, the radar returns are often cluttered by interference, obscuring the signal.
