掃瞄誤差 的英文怎麼說
中文拼音 [sǎomiáowùchā]
掃瞄誤差
英文
scanning errors-
To ensure the reliability of tracking the target, signal attenuation and boresight error must be predicted accurately
要保證導彈跟蹤目標的準確性,必須預測在給定掃描角下的信號衰減和瞄準誤差。The radiation patterns with and whitout radome are calculated, and the angle difference in the maximum field point of their main clot show the bse of the radome, the bse from - 15 degree to 15 degree in direction, that been calculated and compared with the excited experimented data shows they coincide quite well
有天線罩時的遠區場和沒有天線罩時的遠區場相比較,兩個主波束對應的角度差即是天線罩的瞄準誤差,本文對方位掃描角從負15度到正15度進行分析。The radiation patterns at different scan angle from - 20 to 20 degree are presented, and the angle difference between the maximum / minimum field points of their main beam shows the bse of the radome. at different frequencies, the radiation from the antenna has been discussed when azimuth scan angle ranges between - 20 degree and 20 degree. the relationship between
200 ~ 200范圍內天線的和方向遠區場、方位差方向遠區場;得到方位瞄準誤差、瞄準誤差斜率和功率傳輸系數隨掃描角和入射波頻率的變化關系;並將所得數據與文獻數據進行比較,表明間接射線法簡單、有效且精度較高。
