Carrier to noise ratio
DEFINITION
In a modulated signal (i.e. the pulse), the carrier to noise ratio is the ratio of the signal power to the signal noise power. English
Una misura della forza del segnale di ritorno al lidar. Italian
En una señal modulada (ej. pulsada), cociente entre la potencia de la señal y la potencia del ruido de esa señal. Spanish
在调制信号中，载波噪声比是信号功率与信号噪声功率的比值。 cn

- CNR
EDITORIAL NOTE
- A measure of lidar return signal quality. Is the signal to noise ratio of the modulated signal sent to probe the atmosphere and defines the lidar data availability. If CNR is below a certain threshold the information carried by the backscattered (modulated) light is discarded. Often used interchangably with SNR.
