detection.","After extracting the target signal, the targets should be detected from the MTI signal.","As some of the radar sensors have narrow beamwidth antenna, thus, data might become unavailable if the person in not in the line of sight of the radar.","Some radar multidisciplinary optimization can adopt collaborative design and concurrent design, which can shorten the cycle as much as possible.","In these scenarios, a set of TOAs corresponding to each pair of transmitting and receiving antennas can be estimated, and an adequate set of the ellipse pairs can be created."]
