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 With Matrix Completion
IEEE Journal of Selected Topics in Signal Processing, 2015It was recently shown that MIMO radars with sparse sensing and matrix completion (MC) can significantly reduce the volume of data required by MIMO radars for accurate target detection and estimation. In MIMO-MC radars, the subsampled target returns are forwarded by the receive antennas to a fusion center, partially filling a matrix, referred to as the ...

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.

Minimax Robust MIMO Radar Waveform Design
IEEE Journal of Selected Topics in Signal Processing, 2007We consider the problem of minimax robust waveform design for multiple-input multiple-output (MIMO) radar based on mutual information (MI) and minimum mean-square error (MMSE) estimation for target identification and classification. Recognizing that a single, precise characterization of target power spectral density (PSD) is rare in practice, we assume

Waveform design for compressively sampled ultrawideband radar
Journal of Electronic Imaging, 2013Compressive sensing makes it possible to recover sparse target scenes from under-sampled measurements when uncorrelated random-noise waveforms are used as probing signals. The mathematical theory behind this assertion is based on the fact that Toeplitz and circulant random matrices generated from independent identically distributed (i.i.d) Gaussian ...

Joint automotive radar-communications waveform design
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017The paper studies the problem of waveform design for a joint Radar-Communications (RadComms) system in an automotive setting characterized by a multitarget environment. The envisaged joint waveform allows exploitation of existing infrastructure to support additional functionalities.

MIMO Radar Waveform Design in the Presence of Clutter
IEEE Transactions on Aerospace and Electronic Systems, 2011Waveform design for target identification and classification in multiple-input multiple-output (MIMO) radar systems has been studied in several recent works. In previous works, optimal signals for an estimation algorithm are found assuming that only signal- independent noise exists. This work extends previous research by studying the case where clutter

Reduced PMEPR Multicarrier Radar Waveform Design
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019Multicarrier radar waveforms have many desirable properties for many radar applications. The well known multifrequency complementary phase-coded (MCPC) radar waveforms based on the consecutive ordered cyclic shift (COCS) design can achieve a low peak-to-mean envelope power ratio (PMEPR).

Waveform Design and Optimization in Radar Sensor Network
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010We investigate the use of information theory to design waveforms for the measurement of extended radar targets in radar sensor networks (RSN). The different channel gains for transmitting signals from different radar sensors are introduced to model the radar system channel.
