中文摘要 | 本研究係討論雷達測繪在相對運動中,方位變化率、距離變化率以及相對速率對於目標觀測誤差之大小有無特定之關係。本研究設計六種相對運動狀況,分別就不同之方位變化率、距離變化率以及相對速率比較各種相對運動的觀測誤差之大小。每種相對運動分別觀測60次。測試結果顯示各種相對運動之觀測誤差值均呈常態分配 (Normal Distribution)。以測試統計量Z來檢定各種相對運動之觀測誤差絕對值之平均數差異。結果除RML2 vs. RML5 之方位觀測誤差絕對值平均數之差異不顯著外,其餘均達顯著水準 (Significance Level; α = 0.05)。比較結果顯示方位變化率愈大者,其方位觀測誤差愈大。距離變化率愈大者,其距離觀測誤差愈大。相對速率愈大者,方位與距離之觀測誤差愈大。 |
英文摘要 | This paper focuses on the relations of observer's errors effected by change rates of bearing distance and the relative speed of targets while observer engages in Radar Plotting. There are six relative models designed in this project. There are 60 observations in each model. All errors of observations in six models show normal distribution. The differences of mean of absolute value of observation errors are performed by Z-test (α= 0.05). All differences exceed significance level except RML2 vs. RML5 in bearing. The conclusion is "The more change rate of bearing, the more bearing errors; the more change rate of distance, the more distance errors; the faster relative speed, the more observation errors." |
