A Design of TMA Functions for New Submarine Combat System

Ren Keming,Pan Yue,Wang Yan

Strategic Study of CAE 1999, Volume 1, Issue 3, Pages 31-34

Abstract:

This paper overviews a few methods of TMA (target motion analysis), such as only bearing TMA, multipleinformation fusion TMA, bearing-Doppler TMA, distance estimation with bearing and noise energy, matched-fieldlocation combined with TMA etc.

We enhances the TMA functions from the point of view of submarine combat system, fully applying, added the manual TMA function, and designed a display on which the operator can easyly observe TMA

A Survey of the Observability for Single Observer Passive Location

Deng Xinpu

Strategic Study of CAE 2007, Volume 9, Issue 11, Pages 54-62

Abstract:

A basic requirement for passive state estimation using single observer is the existence of a unique tracking solution. This leads to the question of observability. The target state is observable over the time interval if, and only if, it is uniquely determined by the measurements taken in that interval. In this paper, the state-observability problem for passive target tracking by angle measurements is analyzed using three methods: the geometrical method, the elementary algebraic method and linear system method. The observability for target tracking with frequency measurements is also analyzed. Degree of observability is discussed. And a concise review of papers on observability analysis is presented.

Measurement of trimethylamine concentration and evaluation of pig meat natural quality by a spectrophotometric method

Mohammod Abdul HAMID,Xi WANG,Xiangdong DING,Chuduan WANG,Xingbo ZHAO

Frontiers of Agricultural Science and Engineering 2014, Volume 1, Issue 3, Pages 236-241 doi: 10.15302/J-FASE-2014034

Abstract: Pig meat off-flavor is attributed to trimethylamine (TMA) concentration, and it is considered as theIn this study, TMA concentrations in pig meat were determined, and the interactions with breed and genderIn addition, the TMA threshold for meat off-flavor and pig meat natural quality was measured in relationThe results indicated positive effects on the precursor of the fishy off-flavor and the TMA thresholdNative breeds were found to have lower TMA concentrations than European breeds ( <0.01), and females
