Apart from basic orthogonality, cognitive multiple-input multiple-output (MIMO) radar waveforms should have the capacity of restraining spectral interferences in complex environment. Constant-modulus waveforms are also desired for the radio frequency (RF) amplifiers. Based on above considerations, this paper proposes an optimization method to design cognitive MIMO radar waveforms with constant modulus...
Inspired by a cognitive radar in exploiting its environment to update current operation parameters and frequency diverse array (FDA) in offering a range-dependent beampattern due to the employment of frequency increments across the elements, this paper proposes a moving-target tracking approach to achieve cognitive radio frequency stealth using an FDA antenna for surveillance applications. Since surveillance...
Different from a phased-array, frequency diverse array (FDA) offers a range-dependent beampattern. By jointly utilizing the advantages of cognitive radar in environment sensing and FDA with range-dependent transmit beampattern, this paper proposes a cognitive target tracking scheme using FDA radar for increased output signal-to-interferences plus noise ratio (SINR) performance due to its range-dependent...
