MISL-based colocated MIMO radar waveform coefficients matrix design for beampattern matching

Fast Transmit Beamforming for Large Planar MIMO Radar

“…Using a similar method, the Ref. [22] has formed desired beampatterns with lower sidelobe levels for generalized MIMO configurations.…”

“…In this paper, we consider a large planar array, and also design a weight matrix to connect the antennas and orthogonal waveforms as same as the approach in Refs. [21,22]. In addition, we propose a cyclic (or iterative) optimization algorithm based on Fast fourier transform (FFT) to obtain the weight matrix, which provides an opportunity for a large planar array to employ the MIMO technique.…”

Constant-Modulus-Waveform Design for Multiple-Target Detection in Colocated MIMO Radar

“…However, with the increase of the number of antennas, the optimal transmitted waveforms or covariance matrix of the transmitted waveforms cannot be figured out immediately due to heavy computation. A more efficient approach was proposed to synthesize transmitted signals by designing a weight matrix given a set of orthogonal waveforms [9,10,11]. By optimizing the weight matrix, the paper [9] focused the transmitting energy within a certain spatial sector to improve the Signal-to-Noise Ratio (SNR) gain.…”

“…By optimizing the weight matrix, the paper [9] focused the transmitting energy within a certain spatial sector to improve the Signal-to-Noise Ratio (SNR) gain. Using a similar method, a study [10,11] formed the desired beam patterns with lower sidelobe levels for generalized MIMO configurations. Then, the waveform-design problem was converted into the optimization of the weight matrix with the assumption of complete orthogonal waveforms.…”
