如果被(bei)(bei)探(tan)測(ce)(ce)物(wu)(wu)體(ti)始(shi)終在(zai)合(he)適(shi)的(de)(de)(de)(de)角度(du)(du)，那超(chao)聲(sheng)波傳(chuan)感器將會(hui)獲得正確的(de)(de)(de)(de)角度(du)(du)。但是(shi)不幸的(de)(de)(de)(de)是(shi)，在(zai)實際(ji)(ji)使用中(zhong)，很少被(bei)(bei)探(tan)測(ce)(ce)物(wu)(wu)體(ti)是(shi)能被(bei)(bei)正確的(de)(de)(de)(de)檢(jian)測(ce)(ce)的(de)(de)(de)(de)。其中(zhong)可能會(hui)出現幾種誤差：三(san)角誤差,當被(bei)(bei)測(ce)(ce)物(wu)(wu)體(ti)與傳(chuan)感器成(cheng)一(yi)定角度(du)(du)的(de)(de)(de)(de)時候，所探(tan)測(ce)(ce)的(de)(de)(de)(de)距(ju)離和(he)實際(ji)(ji)距(ju)離有個(ge)三(san)角誤差。鏡(jing)面反(fan)(fan)射,這(zhe)個(ge)問題和(he)高(gao)中(zhong)物(wu)(wu)理中(zhong)所學的(de)(de)(de)(de)光的(de)(de)(de)(de)反(fan)(fan)射是(shi)一(yi)樣的(de)(de)(de)(de)。在(zai)特定的(de)(de)(de)(de)角度(du)(du)下，發出的(de)(de)(de)(de)聲(sheng)波被(bei)(bei)光滑的(de)(de)(de)(de)物(wu)(wu)體(ti)鏡(jing)面反(fan)(fan)射出去，因(yin)此(ci)無法產(chan)生回波，也就無法產(chan)生距(ju)離讀數。這(zhe)時超(chao)聲(sheng)波傳(chuan)感器會(hui)忽視這(zhe)個(ge)物(wu)(wu)體(ti)的(de)(de)(de)(de)存在(zai)。多(duo)次(ci)反(fan)(fan)射,這(zhe)種現象在(zai)探(tan)測(ce)(ce)墻(qiang)角或者類似(si)結構的(de)(de)(de)(de)物(wu)(wu)體(ti)時比(bi)較常見。聲(sheng)波經過多(duo)次(ci)反(fan)(fan)彈(dan)才被(bei)(bei)傳(chuan)感器接(jie)收到(dao)，因(yin)此(ci)實際(ji)(ji)的(de)(de)(de)(de)探(tan)測(ce)(ce)值(zhi)(zhi)并不是(shi)真實的(de)(de)(de)(de)距(ju)離值(zhi)(zhi)。
