MIMO Radar Ambiguity Properties and Optimization Using Frequency-Hopping Waveforms [PDF]

, 2008
The concept of multiple-input multiple-output (MIMO) radars has drawn considerable attention recently. Unlike the traditional single-input multiple-output (SIMO) radar which emits coherent waveforms to form a focused beam, the MIMO radar can transmit ...
