如果你是问radar是什么词的话 （ra）dio （d）etecting (a)nd (r)anging
sonar是 （so）und (na)vigation (r)anging

以后这种问题用伟氏大辞典就解决了

雷达： Radio Detection and Ranging （rader）
The word RADAR was created in 1942 as an acronym (words with letters that each have its own meaning) for Radio Detection and Ranging

声纳：Sonar
sound navigation and ranging
