Course Outcomes: At the end of the course, students will be able to:

1. Describe the radar fundamentals.
2. Analyze the radar signals.
3. Explain the working principle of pulse Doppler radars, their applications and limitations.
4. Describe the working of various radar transmitters and receivers.
5. Analyze the range parameters of pulse radar system which affect the system performance.

Question paper pattern:

  • Examination will be conducted for 100 marks with question paper containing 10 full questions, each of 20 marks.
  • Each fiJll question can have a maximum of 4 sub questions.
  • There will be 2 full questions from each module covering all the topics of the module.
  • Students will have to answer 5 full questions, selecting one full question from each module.
  • The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
