Unitary design of radar waveform diversity sets
Digital Signal Processing, 2008In this work, multiple radar waveforms are simultaneously transmitted, emitted from different ldquovirtualrdquo antennas. The goal is to process the returns in such a way that the overall ambiguity function is a sum of ambiguity functions better approximating the desired thumbtack shape.

Detection performance is optimized and range and doppler both improved by maximizing the SNR. Since this needs the pulse to have high energy, long pulses are required unless a very high power transmitter is available. Long pulses also permit good doppler accuracy, but, for simple pulses, give poor range accuracy.

Waveform Design for MIMO Radars
IEEE Transactions on Aerospace and Electronic Systems, 2007We consider the problem of waveform design for multiple input/multiple output (MIMO) radars, where the transmit waveforms are adjusted based on target and clutter statistics. A model for the radar returns which incorporates the transmit waveforms is developed. The target detection problem is formulated for that model.

Periodic Binary Waveform Design for MIMO Radar
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019Most commercial multi-input multi-output (MIMO) radar systems, such as the increasingly popular automotive radar systems, use linear frequency modulated continuous wave (LFMCW) as probing sequences. However, mutual interference problems become increasingly severe as these radar systems become widely used.

Optimal radar waveform design for moving target
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Radar performance improvement through waveform optimization has been an ongoing topic of research recent years. In this paper, we use the optimal waveform design method to deal with the moving target in the clutter and noise. Neyman-Pearson detector criterion is used to maximize the probability of target detection. The optimal waveform is then designed

Sixth International Conference on `HF Radio Systems and Techniques', 1994
HF over-the-horizon radars often use CW transmissions comprising repeated linear FM sweeps. The resolution and sidelobe performance in the range dimension are determined within each sweep, but Doppler information is extracted by processing together the outputs of a number of sweeps.

Constant envelope waveform design for MIMO radar
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010A method for generating constant envelope (CE) waveforms to realise a given covariance matrix for a closely spaced MIMO radar system is proposed. In contrast to available algorithms, the technique provides closed form solutions for finding the required waveforms and suggests that waveforms can be chosen from finite alphabets such as binary-phase shift ...

On waveform design for MIMO radar with matrix completion
2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014In matrix completion based MIMO radars, the data matrix coherence, and consequently the performance of matrix completion depend on the transmit waveforms. It was recently shown that for uniform linear arrays and orthogonal waveforms, the optimal choice for waveforms are white-noise type functions.

Optimal and robust waveform design for MIMO radars
2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009Waveform design for Target identification and classification in MIMO radar systems has been studied in several recent works. While the previous works considered signal independent noise, here we extend the results to the case where signal-dependent noise, clutter, is also present and then we find the optimum waveform for several estimators differing in
