The potential efficiency of optimal interperiod processing (IPP) of coherent batch radio pulses reflected from point air targets against the background of high-power clutter is analyzed during the radar operation in the pulse-Doppler mode with middle frequency of probing at ambiguous measurements of target range and velocity. This efficiency is compared with IPP efficiency during the radar operation in the coherent pulse mode. The analysis is performed at constant and variable probing intervals when the time span of the clutter source zone is both less and greater than the probing interval in pulse-Doppler radar, i.e. in the absence and presence of superposition of clutter from different range sections. The cases of complete match of parameters of clutter superposition are analyzed at different radial velocities of equipotent clutter layers, and also the cases of superposition of nonequipotent clutter layers, the powers of which are inversely proportional to the squared distance from their sources. In addition, the wobbling of intervals of signal probing is also taken into account.
