Radar waveform design in active communications channel [PDF]

open access: yes2013 Asilomar Conference on Signals, Systems and Computers, 2013
In this paper, we investigate spectrally adaptive radar transmit waveform design and its effects on an active communication system. We specifically look at waveform design for point targets. The transmit waveform is optimized by accounting for the modulation spectrum of the communication system while trying to efficiently use the remaining spectrum ...

Information-Theoretic Optimal Radar Waveform Design

IEEE Signal Processing Letters, 2017
In 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.

MIMO radar waveform design

open access: yes, 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.

Limited Feedforward Waveform Design for OFDM Dual-Functional Radar-Communications [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
We consider the problem of time-frequency waveform design for an OFDM dual-functional radar-communications (DFRC) system that communicates with an OFDM receiver while simultaneously estimating target parameters using the backscattered signals.

Robust Waveform Design for MIMO Radars

IEEE Transactions on Signal Processing, 2011
The 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 may be unknown, e.g., the target scattering covariance matrix and the disturbance covariance matrix.

Radar waveform design for detection of weapons

2010 2nd International Workshop on Cognitive Information Processing, 2010
We 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 ...

Optimal waveform design for cognitive radar

2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008
A 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 ...

Waveforms design for modern and MIMO radar

Eurocon 2013, 2013
One of the main focus of the research in modern radar systems, as MIMO (Multiple Input Multiple Output) radar and multifunction/multistatic radar, is the waveforms design and optimization in order to get a low degradation in the main lobe (low Signal to Noise Ratio loss), a low Peak Side-Lobe Ratio (PSLR) and good orthogonality properties.

Wideband MIMO Radar Waveform Design

IEEE Transactions on Signal Processing, 2019
We consider the design of wideband multiple-input multiple-output (MIMO) radar waveforms to approximate a desired beampattern and achieve prescribed space-frequency nulling in a space-frequency region of interest. A general design model involving modulus, power, and energy constraints on the probing waveforms is introduced.
