Embodiment Construction

[0009]In view of the foregoing background, it is therefore an object of the non-limiting exemplary embodiment(s) to provide a pulse radar system and method that has long range unambiguous image reflections at high pulse repetition frequency (PRF), long range high resolution radial velocity not limited by Doppler Nyquist limiting, improved signal sensitivity, and strong in-band interference rejection, thereby improving existing radar by increasing the transmission pulse rate by uniquely tagging each outgoing pulse so they can be easily separated when received. These and other objects, features, and advantages of the non-limiting exemplary embodiment(s) are provided by a pulse radar system including a pulse generator located at a first location and configured to create at least one pulse having a modulation signal and a carrier signal. Such a modulation signal is configured to be changed with each successive one of the at least one pulse such that the at least one pulse is easily sepa...
