The following four (4) books are provided FREE with your registration, (total list price value $519):

  1. “Radar Technology”, Dr. Eli Brookner (Editor), Lexbook, 282 Marrett Rd., (formerly published by Artech house), Hardcover $123 list price.

  2. “Aspects of Modern Radar”, Dr. Eli Brookner (Editor), Lexbook, 282 Marrett Rd., (formerly published by Artech house), Hardcover $131 list price.

  3.  “Radar System Analysis and Modeling” David K. Barton, Artech House, 2004, Hardcover $129 list price. One very useful feature of this new book is the inclusion of a CD with the Mathcad® Version 11 programs used to generate the curves in the book. Thus the reader can change the parameters of the figures to suite his case of interest. Also, the CD includes an Evaluation Version Mathcad® Version 11 Single User Edition. This is a full version of the $2000 Mathcad software which the user can use for 120 days after installation. Mathcad is an easy, user friendly language.

  4. “Tracking and Kalman Filtering Made Easy”, by Dr. Eli Brookner, John Wiley Interscience,  1998, Hardcover list price $110. Fantastic book, gives  extremely  simple, geometric and physical introduction to the voltage methods for sidelobe canceling, least-squares filtering, G-H filtering and Kalman Filter. How they are all related is shown. Systolic array implementation given. The latest printings,  (4th and beyond) have new sections; when Kalman Filter is optimal; other forms of Kalman Filter and ; a small section on Non-linear  filters.

 

This course is geared to those unfamiliar as well as those experienced with radar design. It covers radar basics and advanced topics from a simple, physical point of view.  It covers present technology and techniques as well as future trends and techniques.

This course is an updated version of the Radar Technology course given previously.  Those who have taken the Radar Technology previously should find it worthwhile taking this revised version. Extra lecture added in order to include coverage of NEW material consisting of (but not limited to): Radar height-range coverage diagram determination using the powerful SPAWAR’s (updated May ‘05)  AREPS 3.3 and EREPS 3.0 programs. The AREPS program provides coverage for arbitrary propagation conditions (ducts [evaporation, surface, or elevated], subrefraction or superrefraction) and terrain conditions (based on DTED data). The latest powerful AREPS program accounts  for surface roughness scattering and evaluates sea and land clutter backscatter versus range. The attendees will be informed on how to obtain FREE, these PC based, versatile programs,  valued at thousands of dollars; Also covered will be: Anomalous Propagation and what to do about it; STAP, AMTI, DPCA; Synthetic Aperture Radar (SAR) processing; digital beamforming: System Temperature

Updated course is framed around books Radar Technology (1977) and Aspects of Modern Radar (1988) edited by Eli Brookner; updated version of the book “Tracking and Kalman Filtering Made Easy” (1998) by Eli Brookner; and new version of  Barton’s radar systems book “Radar System Analysis and Modeling” (2004).

The Radar Technology textbook for the course gives parameters for 96 American, Russian, French, Dutch and English radars (Table 1).  Photos for nearly all 96 radars plus others are provided in the text.  The Aspects of Modern Radar book updates this table giving the parameters of over 200 surface and airborne radars.

The recent book “Tracking and Kalman Filtering Made Easy”, takes the mystery and drudgery out of the g-h, g-h-k and Kalman filters.  This book covers the filters from simple physical and geometric approaches.  Extensive, simple and useful design equations, procedures and curves are presented.  Extensive homework problems and their solutions are given.  Covered in simple terms; is the voltage least-squares filtering problem, the orthognal transformations (Givens, Gram-Schmidt and Householder) for doing least-squares filtering, and finally the extended Kalman filter.

For the beginner, basics such as the radar equation, MTI (Moving Target Indicator) and pulse doppler processing, antenna-scanning techniques, pulse compression, CFAR, RAC and SAW devices are explained in simple terms.

For the experienced, the most recent radar technology and techniques are covered in simple terms, e.g., the detection of low flying, low cross-section targets, techniques for coping with multipath when tracking low flying targets (e.g. the use of an even difference over sum pattern), off-axis monopulse, complex monopulse and multiple carrier frequencies, the Dome antenna, CCDs, BBDs, SAW devices, SAW monolithic convolvers, microstrip antennas, ultra low antenna sidelobes (<-50 dB), stacked beam and phased array systems, (1-D, 2-D, Limited Field of View [LFOV]), Moving Target Detection (MTD), fiber optics.  These will be explained so that the inexperienced can follow as well.

For both the novice and experienced covered are tracking, prediction and smoothing in simple terms (the mystery taken out of g-h and Kalman filters); the latest developments in solid state discrete and monolithic microwave integrated circuits (MMICs), from UHF to mm waves and in tubes (e.g., gyrotrons), state-of-the-art and future trends in signal digital processing architectures and hardware; strip and spotlight synthetic aperture radar (SAR): Displaced Phase Center Antenna (DPCA) technique; trends in signal and data processing; FPGAs; systolic processing; GaAs technology;  digital beam forming; Adaptive-Adaptive Array Processing for near optimum jammer suppression with orders of magnitude reduction in computation complexity and in transient time.
