This book describes monopulse implemented with Active Electronically Scanned Arrays (AESAs). Both phase- and amplitude-comparison monopulse are addressed. Limitations imposed by AESAs and non-ideal performance due to quantization, vector modulator noise, and element failures are discussed. The author addresses monopulse using modern low-cost AESAs where the hardware is often non-ideal and where one must carefully balance cost and complexity. The relationship between AESA antenna gain and monopulse measurement is shown and is used to construct an accurate “first-principles” simulation of the monopulse measurement process including both Additive White Gaussian Noise and non-ideal hardware effects. For those unfamiliar with monopulse, this book discusses both the theory and implementation of monopulse for application in modern AESA antennas. For those familiar with the ideal performance of monopulse, the book shows the sensitivity of monopulse accuracy to non-ideal hardware implementations, particularly in AESAs. For those familiar with both, the book discusses Monte-Carlo techniques for simulating the measurement process to obtain realistic, non-ideal monopulse performance vs signal-to-noise ratio. And for those working in radar, the book explains the relationship between one-way monopulse and the monostatic radar case with two-way propagation utilizing the same antenna for both transmit and receive. Shows the relationship between monopulse theory and implementation in modern AESAs; Illustrates the relationship between AESA antenna gain and monopulse accuracy; Discusses the limitations of AESA hardware implementation on simultaneous sidelobe control and monopulse measurement.

Detailed closed-loop bandwidth and transient response approach is a subject rarely found in current literature. This innovative resource offers practical explanations of closed-loop radar tracking techniques in range, Doppler and angle tracking. To address analog closed loop trackers, a review of basic control theory and modeling is included. In addition, control theory, radar receivers, signal processors, and circuitry and algorithms necessary to form the signals needed in a tracker are presented. Digital trackers and multiple target tracking are also covered, focusing on g-h and g-h-k filters. Readers learn techniques for modeling digital, closed-loop trackers. The radar circuitry/block diagrams necessary for range, Doppler and angle tracking are presented and described, with examples and simulations included. Factors such as noise and Swerling type fluctuations are taken into account. In addition to numerous worked examples, this approachable reference includes MATLAB® code associated with analysis, simulations and figures. The book contains solutions to practical problems, making it useful for both novice and advanced radar practitioners. Software will be available for download on this page.
