radarThe performance of adaptive multiple-input multiple-output (MIMO) radar waveforms is examined. We begin by defining a metric, called "MISO cancellation ratio", for numerically screening MIMO waveforms so as to assess their clutter cancellation performance. Next, we evaluate the MISO cancellation...
and anti-jamming characteristics. After nearly 20 years of in-depth research by scholars, the MIMO radar theory based on orthogonal waveforms has significantly improved. It has been widely applied in fields such as automobile-...
Moreover the signal to interfere plus noise ratio(SINR) and the achievable sum rate do not deteriorate when the transmit power is high. Further,the upper bound of the achievable sum rate can be more than twice that of the half duplex. 展开 关键词: full duplex self-interference cancellation ...
4. For cognitive radar waveform design problem, we researched the constant envelope waveform design methods in the presence of colored noise and in the presence of clutter, respectively. Under maximum output signal-to-noise ratio (SNR) and signal-to-clutter-and-noise ratio (SCNR)) criterion, ...
