This method … WebThis particular split allows a minimum detectable reflectivity factor below −15 dBZ throughout the profile. As sensitivity decreases with height, the transition to the region of the profile associated with the next chirp brings a sharp increase in sensitivity, while the vertical resolution and the Nyquist velocity interval decrease.
