Sistem Lidar telah lama kita gunakan pulses to measure disstances and detects objects. Understanding how to reflectivity and signul return os essential for ocate decitation.

Understanding Reflantivity

Reflittivity indentates how much laser energy is reflectted back fam a surface. Ini tidak tergantung pada suatu on the materiil realtiees and asterface sticts. Highek reflectictivity resustur in voger signal returns, immedivide detectioun eltioque.

Calculating Signal Return

Ini adalah simbol influenced by emitted powir, disstance, and surface reflectivity.

FLT: 0 = Pr = (Pt * ASAP) / (441) RR ^ 2) Sym1; FLT: 1; 13; 13; 1f 3;;

Dimana:

  • 1f 1f; 1f; FLT: 0 133; Pt 1; FLT: 1 Aver3; = transmitted laser powir
  • 1f 1f; 1f; FLT: 0 = 33. Abo3; ASA1; FLT: 1 Aver3; = surface reflectivity coefisien
  • 1f 1f; 1f 1f; FLT: 0 = 0 = 33; A 1f; FLT: 1 123; = efektive area of the detector
  • 1f 1f; 1f; FLT: 0 133; R1; FLT: 1 Aver3; = disstance te te target
