Joint beat-spectrum averaging in a multi-frequency MIMO radar approach on a slow-fluctuating object range detection

Radar is widely applied in detecting such as aircrafts, ships and motor vehicles, mainly for security and safety purposes. However, a small object is hard to be detected moreover if it is fluctuating. Meanwhile, utilisation of a multiple-input multiple-output (MIMO) in the radar configuration has...
