, 2012 In this chapter, we review various probing waveform transmission schemes for multiple-input multiple-output (MIMO) radar with co-located antennas. An orthogonal probing waveform set is required to separate the transmitted waveforms at the receiver side to achieve a large virtual array size afforded by the MIMO radar.

Cognitive radar waveform design for spectral compatibility
2016 Sensor Signal Processing for Defence (SSPD), 2016Radar performance is strongly dependent on the transmitted waveform and its parameters which must be adapted to the surrounding environment, radar mission, goal, and task. Waveform diversity is a relatively new paradigm involving a continuous variation and adaptation of the transmitted signal to dynamically optimize the radar performance and fulfill ...

In this paper, under the peak-to-average power ratio (PAR) and energy constraints on the transmit waveforms, a new efficient weighted $\ell _p$-norm metric (with $p\geq 2$) is introduced for colocated wideband/narrowband multiple-input multiple-output ...

A Comparative Study of Multiple Radar Waveform Design Techniques
2020 Second International Conference on Inventive Research in Computing Applications (ICIRCA), 2020The pulse compression terminology in radar systems emerges as a solution to problems such as achieving energy of a long pulse and resolution of a short pulse.

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.

Waveform design for TDM-MIMO radar systems
Signal Processing, 2020Abstract In this paper, we propose an efficient algorithm based on second order cone programming (SOCP) to design waveform for time-division-multiplexing (TDM) multiple-input-multiple-output(MIMO) radar systems. To this end, we optimize Peak Sidelobe Level (PSL) of the transmit sequence with constant modulus constraint.

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

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 ...

Constant Modulus MIMO Radar Waveform Design With Minimum Peak Sidelobe Transmit Beampattern
IEEE Transactions on Signal Processing, 2018This paper addresses the problem of minimum peak sidelobe transmit beampattern design for colocated multiple-input multiple-output radar systems. Two new methods are proposed to achieve it via designing constant modulus (CM) waveforms directly: One is to

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.
