Abstract :
Often a requirement of radar is a high pulse repetition frequency, as such range ambiguities are a consequence of this requirement. One approach to resolve said ambiguities is to use a non-uniform PRF. The interest in this paper is to utilize a uniform PRF and pulse diversity to resolve a single or multiple range ambiguities through temporal coding. An algorithm will be introduced that is completely scalable to any type of scenario that will quickly create a custom set of M unique transmit codes that can be used at every pulse of the transmitter in order to resolve range ambiguities.
