The purpose of this article was to use ISAR to determine the distance between the receiving antenna and the transmitting antenna. Once a systematic approach has been determined, this article could be used on a spacecraft to locate debris in the path of the carrier. Using low frequency radar that has the transmitting pulse built within the converters, the authors transmitted the data and determined the distance between the two antennas according to the time delay of the radar. Using amplified signals, the relationship between the distance and the time delay for the radar were calculated for each case. Additionally, these results were used to visualize in real-time the data transpired between the receiver and transmitter.
