Distance estimation is an integral part of localization in Euclidean space and the first step of any localization algorithm. In the underwater domain the distance is estimated by measuring the propagation delay of a pressure wave in the acoustic frequency range. In the process a known waveform is correlated with a received signal in order to determine the time instance of the wave incident at a receiver, thus the correlation properties of the known waveform are of upmost importance. This paper evaluates the suitability of the communication standard called JANUS for the generation of waveforms for distance estimation while still adhering to the standard. Additionally the correlation properties of the resulting waveforms are compared to slight adaptations to the JANUS standard and less restricted FH-FSK waveforms commonly used in continuous wave sonar and radar systems
