Note to entry: The peak side lobe ratio is usually expressed in decibels (dB) and computed as follows ${\displaystyle \text{PSLR}=10{\log }_{10}^{}\left\{\frac{P_{\text{sidepeak}}}{P_{\text{mainpeak}}}\right\}}$ where ${\displaystyle P_{\text{mainpeak}}}$ is the peak power of the main lobe; P_"sidepeak" is the peak power of the largest side lobe.
