In this paper, we considered the problem to improve the performance of the UUV when the navigation error exists in the application of target acquisition. The mother ship guides the UUV to acquire the target based on the location information sent back by the UUV. Since the navigation error exists, the discovery probability of the target has been highly decreased. Based on the modeling of the navigation...
This study aims to examine the suitability of Globcover land cover dataset for its accuracy in mapping and monitoring cropland in Northeast China three provinces. To do so, Globcover dataset was compared with the reference national land cover dataset 2000 (NLCD-2000) for assessing the aggregated area and spatial extent of cropland across the study area. The results showed that the accuracy in Jilin...
This paper presents a new progressive distributed estimation scheme (DES) along with the power scheduling among sensors under AWGN channels. The progressive DES consists of a transmission bit allocation scheme and a quasi best linear unbiased estimate (BLUE) of the unknown parameter at each sensor. This scheme is shown to outperform the traditional progressive DES. Moreover, the power scheduling among...
Estimating the number of sources impinging on an array of sensors is a well known and well investigated problem. Based on the rotational invariance property between two identical subarrays, using the Lanczos algorithm to fast compute the analysis filterbank of multi-stage wiener filter, a novel method for fast estimating the number of wideband sources is proposed in this paper. Unlike the traditional...
