The specification of the waveform employed by any radar system has always been a key factor in determining performance and application. In recent years there has been a trend towards ever greater degrees of digitization and more widespread use of solid state power amplification in radar systems.

Digitally coded radar waveforms can be used to obtain large time-bandwidth products (pulse compression ratios). It is demonstrated that periodic radar waveforms with zero sidelobes or almost zero sidelobes can be defined. A perfect periodic code is a periodic code whose autocorrelation function has zero sidelobes and whose amplitude is uniform (maximum

The flexibility in the selection of waveforms indicates the performance of Radio Detection and Ranging(RADAR) system. These waveforms help in separation and identification of two targets, which are closely spaced in range or traveling near to each other by the the same speed.

Waveform selection in radar target classification
IEEE Transactions on Information Theory, 2000We apply a sequential experiment design procedure to the problem of signal selection for radar target classification. Radar waveforms are designed to discriminate between targets possessing a doubly spread reflectivity function that are observed in clutter.

Radar waveform design for detection of weapons
2010 2nd International Workshop on Cognitive Information Processing, 2010We present waveform design based on signature exploitation techniques for improved detection of weapons in urban sensing applications. We consider a single-antenna monostatic radar system. Under the assumption of exact knowledge of the target orientation and, hence, known impulse response, matched illumination approach is used for optimal target ...

Phase Retrieval for Radar Waveform Optimization
IEEE Transactions on Aerospace and Electronic Systems, 2012An important problem in radar waveform optimization is the synthesis of discrete time constant modulus signals from Fourier magnitude data. Iterative algorithms for solving this problem have been proposed in the literature, but the algorithms are only applicable in limited cases, and the convergent behavior of these algorithms has not been established.

Generalized DFT waveforms for MIMO radar
2012 IEEE 7th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2012Recently, the Generalized Discrete Fourier Transform (GDFT) with nonlinear phase was introduced to improve the traditional Discrete Fourier Transform (DFT). We take advantage of the phase shaping function (PSF) of GDFT framework to optimize auto- and cross-correlation properties of OFDM frames used to generate radar waveforms.

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 ...
