### Summary

This four-day course is designed for students that have a college level knowledge of mathematics and basic physics to gain the “big picture” as related to basic sensor and weapons theory. As in all disciplines knowing the vocabulary is fundamental for further exploration, this course strives to provide the physical explanation behind the vocabulary such that students have a working vernacular of naval weapons.

• What are radar systems, and how their intended applications control their spectrum and architecture
• What are the key radar parameters and how they’re selected
• What are the principal radar modes of operation
• Radar waves propagation in space and the effects thereof of atmospheric refractivity and surface conditions
• Radar wave scattering from targets and clutter
• Thermal noise and detection in thermal noise
1. Introduction: The general nature of radar: composition, block diagrams, photos, types and functions of radar, typical characteristics.

2. The Physics of Radar: Electromagnetic waves and their vector representation. The spectrum bands used in radar. Radar waveforms. Scattering. Target and clutter behavior representations. Propagation: refractivity, attenuation, and the effects of the Earth surface.

3. The Radar Range Equation: development from basic principles. The concepts of peak and average power, signal and noise bandwidth and the matched filter concept, antenna aperture and gain, system noise temperature, and signal detectability

4. Thermal Noise and Detection in Thermal Noise: Formation of thermal noise in a receiver. System noise temperature (Ts) and noise figure (NF). The role of a low-noise amplifier (LNA). Signal and noise statistics. False alarm probability. Detection thresholds. Detection probability. Coherent and non-coherent multi-pulse integration.

5. The Sub-Systems of Radar: Transmitter (pulse oscillator vs. MOPA, tube vs. solid state, bottled vs. distributed architecture), antenna (pattern, gain, sidelobes, bandwidth), receiver (homodyne vs. super heterodyne), signal processor (functions, front and back-end), and system controller/tracker. Types, issues, architectures, tradeoff considerations.

6. Current accomplishments and concluding discussion.

### Instructors

Dr. Menachem Levitas has forty four years of experience in science and engineering, thirty six of which have consisted of direct radar and weapon systems analysis, design, and development. Throughout his tenure he has provided technical support for many shipboard and airborne radar programs in many different areas including system concept definition, electronic protection, active arrays, signal and data processing, requirement analyses, and radar phenomenology. He is a recipient of the AEGIS Excellence Award for the development of a novel radar cross-band calibration technique in support of wide-band operations for high range resolution. He has developed innovative techniques in many areas e.g., active array self-calibration and failure-compensation, array multibeam-forming, electronic protection, synthetic wide-band, knowledge-based adaptive processing, waveforms and waveform processing, and high fidelity, real-time, littoral propagation modeling. He has supported many AESA programs including the Air Force’s Ultra Reliable Radar (URR), the Atmospheric Surveillance Technology (AST), the USMC’s Ground/Air Task Oriented Radar (G/ATOR), the 3D Long Range Expeditionary Radar (3DLRR), and others. Prior to his retirement in 2013 he had been the chief scientist of Technology Service Corporation’s Washington Operations.
