This report examines the dynamic range performance of narrowband and wideband superheterodyne surveillance receivers. A theoretical review of parameters indicative of the dynamic range performance of each type of receiver is presented. It is seen that for a narrowband superheterodyne receiver, the dynamic range performance can be specified using a parameter based on a single tone at the input. For a wideband superheterodyne receiver, one or more two tone dynamic range parameters are needed. These two tone dynamic range parameters are then used to predict the dynamic range performance of a wideband superheterodyne surveillance receiver currently being built for DREO. Some anticipated dynamic range problems specific to this system are discussed.
