Simplified Radar Equation For the WSR-88D, the only variables that are not fixed are returned power (Pr), reflectivity (Z), attenuation factor (La), and range (R). The fixed variables are combined to create a new term which we will refer to as the radar constant, Cr. By combining the fixed variables into a radar constant, Equation (1) simplifies into where Cr is the radar constant. Solving for Z, the above equation, Equation (3), becomes
By knowing the returned power and range (based on timing), the above equation, Equation (4), estimates target reflectivity. Next Page: Equivalent Reflectivity vs. Reflectivity (Ze vs. Z) |
