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.

Optimal waveform design for cognitive radar
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008A key component of a cognitive radar system is the method by which the transmitted waveform is adapted in response to information regarding the radar environment. The goal of such adaptation methods is to provide a flexible framework that can synthesize waveforms that provide different tradeoffs between a variety of performance objectives, and can do ...

Waveform design for CASA radar network
2006 International Waveform Diversity & Design Conference, 2006The Center for Collaborative Adaptive Sensing of the Atmosphere (CASA), an engineering research center (ERC) established by the National Science Foundation (NSF), will deploy its first generation network of four low-power, short-range, X-band, dual-polarized Doppler weather radars known as NETRAD.

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.

Information-Theoretic Optimal Radar Waveform Design
IEEE Signal Processing Letters, 2017In this letter, we address the problem of designing the optimal radar waveform for the detection of an extended target in a colored noise environment. The locally most powerful detector and the corresponding optimal waveform based on maximizing the detector's performance under a small-signal assumption are derived.

Abstract A confluence of steady advances in radar enabling technologies, and ever increasing demands on radar performance in challenging environments, has afforded a re-examination of the fundamental theoretical framework upon which classical waveform design is based.

Robust waveform design for MIMO radars
2010 IEEE International Symposium on Information Theory, 2010The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely-spaced antennas is addressed here. Robust design is needed as a number of parameters are unknown, e.g., the target scattering covariance matrix and, possibly, the clutter covariance matrix.

Classical radar waveform design
2012The waveform determines the delay-Doppler response of a radar system. From that response, one can derive the radar's range and velocity resolution and their ambiguities. This chapter explains the concept and motivation for pulse compression. It then describes narrow-band signals and their major signal processing and analysis tools - the matched filter ...

Adaptive Noise Waveform Design for Radar
2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009This paper introduces an adaptive radar waveform technique where a standard LFM waveform is used as an initial seed. The seed waveform is changed using a phase-only adaptive technique to minimize the resulting waveform's power in specific areas associated with in-band and adjacent-band spectral regions.

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).
