The proposed algorithm does not require spectral peak search, and can be applied to arbitrary Gaussian noise environment. It can reduce the aperture loss.

该算法无需峰值搜索，适用于任意高斯噪声环境，可有效降低阵列孔径损失。

This method can eliminate the effect of the spatial colored noise and pair the parameters automatically without array aperture loss, and is applicable to senor arrays without an invariance structure.

该方法能够克服空间色噪声的影响，所估计参数自动配对且无阵列孔径损失，并且适用于发射和接收阵列不满足平移不变结构的情况。

youdao

Most of the energy is lost through heat loss through the reactor's wall or through the re-radiation of sunlight back through the device's aperture.

而大多的能量都通过反应器壁的热耗散，或者通过装置开孔的太阳光再发散损失掉了。

youdao

If we assume you have the correct exposure setting for a given scene, and you wish to change the aperture, you must also make a change to the shutter speed or ISO to compensate for the increase or loss of light.
