Announcing a new Open Access book on radar from Professor Nadav Levanon

Radar – Concise Course 

vol. 1 and vol. 2.

Professor Nadav Levanon, of Tel Aviv University, Israel, presents the radar community with a different kind of radar textbook – an open access electronic book, without a publisher involvement. 

Levanon has already published two printed books: Radar Principles (Wiley, 1998) and Radar Signals (Wiley, 2004; so what motivated the switch to an electronic book, easily downloaded at no cost?  Here is a list, starting with general ones, 
Modern workspace of engineers, or young faculty members, hardly contain any printed books.
Publisher’s involvement usually creates a perfect book format, but requires time, money, handling and shipping. The resulted cost, multiplies the author’s share by a large factor.
The royalty issue does not motivate many authors, especially in academia. While large audience does.
Books longevity is shrinking, with the rapid pace of progress in science and technology.
E-books allow easy updates.
In addition to the general arguments, there were issues related to the abrupt switch (Covid-19) from a frontal, in-class academic course, to an online course, which many students could not attend in real time. As the book preface says, the book combines course slides with text uttered or written on the blackboard.  Indeed, the two-columns, landscape layout of the book, offer text on the left and drawings (usually) on the right. Landscape layout does not appeal to publishers but suits computer screens. Color likewise.
Selected topics from the table of contents: 
Volume 1
Radar tasks, history and basic concepts (delay and Doppler)
The radar equation, SNR, coherent pulse train
Aperture and array antennas 
Propagation in the atmosphere
Radar Cross Section (deterministic targets)
RCS and coherency of multi-scatterer statistical targets 
Swerling models (outline and simulations)
Ground effects – multipath and clutter
Matched filter
Ambiguity function (AF)
Periodic AF of a coherent pulse train
Detection (Pd and Pfa)
Coherent and non-coherent integration
Binary integration
Volume 2
Detection with adaptive threshold (CFAR)
Cell averaging CFAR
Order statistics CFAR
Moving target indicator (MTI)
Pulse cancelers and FFT processing
MTI improvement factor
Blind speeds and PRF staggering
Micro Doppler
Pulse compression
o Linear frequency modulation (LFM) and NLFM
o Frequency coding (Costas arrays)
o Binary phase coding
o Polyphase coding and Polyphase Barker
o Stepped frequency
o Complementary pairs
o Multicarrier
Mismatched filters
Radar Measurements 
SNR dependence of delay and frequency measurements
Geometric Dilution of Precision (GDOP)
Synthetic Aperture Radar (SAR)
Interferometric SAR
Continuous Wave (CW) radar
Stretch processing
The content testifies that the book emphasizes radar signal processing and avoids hardware and antenna topics. The material contains basic radar concepts as well as modern developments, with small bias towards Levanon’s own contributions, for which he received the IEEE Picard Medal for 2016.
A prominent feature of the book are the number and quality of the drawings. On the average, there are about two drawings or tables per page. Below is an example. It demonstrates skew-symmetry property on binary code Barker 13. This property is shared by many binary codes exhibiting low autocorrelation integrated sidelobes. Most radar texts mention Barker 13, but few, if any, point out and explain skew-symmetry.

Field of Interest

“The field of interest shall be the organization, systems engineering, design, development, integration, and operation of complex systems for space, air, ocean, or ground environments. These systems include but are not limited to navigation, avionics, mobile electric power and electronics, radar, sonar, telemetry, military, law-enforcement, automatic test, simulators, and command and control."
