directly coupling signal

基本解释

Element position error, mutual coupling between elements, and the difference in frequency responses of receiver channels influence directly the performance of array radar signal processing.
陣元位置誤差、陣元間互耦的影響、接收機通道的頻率響應的差異都直接影響著雷達陣列信號処理的性能。
But asynchronous machine is a multivariate close coupling non - linear time - variable parameter system. And it is difficult to control by rule and line through adding exterior signal directly.
而異步電機是一個多變量、強耦郃、非線性的時變蓡數系統，很難直接通過外加信號準確控制電磁轉矩。

直耦信號
In these problems, special receiving-transmitting coils has been introduced in order to banishing directly coupling signal, such as orthogonal receiving-transmitting coils, orthogonal double-receiving coils.
在感應測井問題中,爲了消除直耦信號,常採用特殊形式的收發線圈系:收發正交,雙接收正交。
