系数分配法

传统的被动测距声纳，对于远程目标采用K系数分配法实现目标的被动定位，而对于近程目标无法实现测距。

For the traditional passive ranging SONAR , K parameter distribution method ( K - PDM ) is used to estimate the time delay to range for far targets .

对于近程目标采用K系数分配法会产生测距模糊问题，但近程信噪比较高，相关峰明显，可以较准确地找到峰值的位置，利用直接测量法进行时延估计。

However , for near targets , K-CDM has the problem of range blurring , then direct measurement method ( DMM ) is used instead the higher SNR and the clear summit .

此外，定义临界距离，并以此为分界点，分别采用K系数分配法和直接测量法对中远程和近程目标进行测距，解决了被动声纳的近程测距模糊问题。

The difficult problem of close range ambiguity in passive sonar is overcome by defining a critical distance and by measuring targets distance using two methods , the direct measurement and a K-distribution .

对于中远程目标，信噪比较低，相关峰不明显，根据跟踪系统提供的方位字，利用K系数分配法进行时延估计；

For far targets , based on azimuth word from tracking system , K parameter distribution method ( K-PDM ) is used to estimate the time delay because of the lower signal to noise ratio ( SNR ) and the vague correlation summit .

为了对比研究地价空间系数分配法得出的立体综合用地地价，提出了加价模型来对地价空间系数分配法得出的地价进行验证分析。
