Indicators (SPIs)
SPIs are a subset of the abilities a student will be able to demonstrate upon successfully completing the course.

Outcome 1 (Students will demonstrate expertise in a subfield of study chosen from the fields of electrical engineering or computer engineering):
1.	Explain radar system design concepts and radar signal processing functions for search and track radar systems and elaborate on the performance versus costs design trade space.
2.	Design, assess and be conversant of the properties of the radar range equation for search, track and volume radar modes.

Outcome 2 (Students will demonstrate the ability to identify and formulate advanced problems and apply knowledge of mathematics and science to solve those problems):
1.	Analyze radar system performance, both in search and track modes, and with low and medium pulse repetition frequencies.
2.	Understand and model radar signal processing algorithms and make quantifiable quality assessments of radar detection and track performance.

Outcome 3 (Students will demonstrate the ability to utilize current knowledge, technology, or techniques within their chosen subfield):
1.	Design and code radar signal processing algorithms and demonstrate radar system operations with simulated transmit/receive data.
