This one-day course is a supplement to the basic course Radar 101, and probes deliberately deeper into selected topics, notably in signal processing to achieve (generally) finer and finer resolution (in several dimensions, imaging included) and in antennas wherein the versatility of the phased array has made such an impact. Finally, advances in radar’s own data processing – auto-detection, more refined association processes, and improved auto-tracking – and system wide fusion processes are briefly discussed. This course is recommended for people with an electrical engineering or equivalent science background.
What You Will Learn:
- Increasing radar performance requirements and corresponding key advances in radar technology and architecture during the past two decades
- Modern digital signal processing techniques including adaptive antenna sidelobes cancellation and STAP, adaptive thresholding, pulse compression, pulse editing, and Doppler processing
- Electronic Steered Arrays (ESA) principles and advantages
- Active Electronic Steered Arrays (AESA) principles and advantages
- Modern advances in waveforms
- Data processing functions including radar tracking
- Introduction: Radar’s development, the metamorphosis of the last few decades: analog and digital technology evolution, theory and algorithms, increased digitization: multi-functionality, adaptivity to the environment, higher detection sensitivity, higher resolution, increased performance in clutter.
- Modern signal processing: Clutter and the Doppler principle. MTI and Pulse Doppler filtering. Adaptive cancellation and STAP. Pulse editing. Pulse Compression processing. Adaptive thresholding and detection. Ambiguity resolution. Measurement and reporting.
- Electronic steering arrays (ESA): principles of operation. Advantages and cost elements. Behavior with scan angle. Phase shifters, true time delays (TTL) and array bandwidth. Other issues.
- Solid state active array (SSAA) antennas (AESA): Architecture. Technology. Motivation. Advantages. Increased array digitization and compatibility with adaptive pattern applications. Need for in-place auto-calibration and compensation.
- Modern advances in waveforms: Pulse compression principles. Performance measures. Some legacy codes. State-of-the-art optimal codes. Spectral compliance. Temporal controls. Orthogonal codes. Multiple-input Multiple-output (MIMO) radar.
- Data processing functions: The conventional functions of report to track correlation, track initiation, update, and maintenance. The new added responsibilities of managing a multi-function array: prioritization, timing, resource management. The Multiple Hypothesis tracker.
- Concluding Discussion: Today’s concern of mission and theatre uncertainties. Increasing requirements at constrained size, weight, and cost. Needs for growth potential. System of systems with data fusion and multiple communication links.
