post-detection signal-noise ratio的意思|示意

The simulation results show that, ICA as the post-processing modules of Joint detection, in the circumstances of high signal to noise ratio, the performance of the system was improved.

仿真结果表明，把联合检测后的数据再次经过ICA后处理模块，在高信噪比的情况下系统的性能有明显的提高。

By comparing the effect between pre-and post clutter reduction, the clutter reduction method increases the signal-to-noise ratio (SNR) of the radar images and improves the detection performance.

从比较结果可以看出，采用该方法抑制这类杂波的效果较明显，通过杂波抑制可以获得更好的图像质量。
