angle of arrival (aoa)の例文
- Based on the facts that time of arrival ( toa ) of the first multipath signal is always most close to that of los propagation and angle of arrival ( aoa ) of the first multipath signal is not always most close to that of los propagation among all multipath signals in nlos propagation environment , a location algorithm is proposed to mitigate the influence of nlos propagation , which effectively reduces the feasible region of a ms in macrocells
- The emitter location methods commonly include : angle of arrival ( aoa ) measurement , time - difference - of - arrival ( tdoa ) measurement and aoa together with tdoa measurement . this paper derive some important techniques and theories bearing upon passive location in this field . three kinds of passive location algorithm in three - dimensional ( 3 - d ) space are deduced based on that of 2 - d space . at the same time each performance is analyzed , each graph of geometric dilution of precession ( gdop ) is emulated for different station position , different measurement error , and different target height . accordingly some valuable academic and emulational results are obtained by myself , which will provide researches in this field with definite technical refrence . at the end of this paper , the passive location method of jtids ( joint tactical distribution systems ) is discussed , which is expected to enforce the tactical performance of jtids in the intending development
