Note to entry: This is often estimated by using the ideal equation for a total-power radiometer, as shown in the following formula. ${\displaystyle \Delta T_{\text{min}}=\frac{T_{\text{sys}}}{\sqrt{B\tau }}}$ where ${\displaystyle \Delta T_{\text{min}}}$ is the radiometric resolution; ${\displaystyle T_{\text{sys}}}$ is the radiometer system temperature; ${\displaystyle B}$ is the bandwidth of the radiometer system ${\displaystyle \tau }$ is the integral time. Radiometric resolution can be also estimated from the variant of this equation that is appropriate for the particular radiometer in question.
