2 sections7 lectures4h 28m total length
  • Introduction to RADAR36:30

    Explore basic radar concepts, including how transmitters and receivers detect and range objects with pulsed or continuous signals, mono-static and bi-static configurations, and the role of frequency bands.

  • Radar Range Measurement43:46

    Explore how radar transmits pulses, uses round-trip transit time to compute range, and mitigates range ambiguity with pulse repetition interval and antenna gain considerations.

  • Radar Range Equation41:19

    Explore the radar range equation, linking transmitted power, antenna gain, effective aperture, and radar cross‑section to maximum range and the minimum detectable signal, and review the radar block diagram.

  • Radar Block Diagram, Radar Frequencies and Application39:50

    Explore the radar block diagram, including transmitter and receiver separated by a duplex, with magnetron or power amplifier, waveform generator, modulator, and receiver chain (mixer, detector, video amplifier).

  • Minimum detecteble signal and available noise power45:30

    Relate the minimum detectable signal to radar receiver noise power by applying a threshold, evaluating the signal-to-noise ratio, and considering available noise power.

  • Modified Radar Equation and signal to noise ratio16:58

    Explore how the modified radar equation incorporates pulse duration, false alarm probability, threshold, and the integration of pulses to analyze the signal to noise ratio at the receiver.

  • Radar cross section of targets and Radar transmitter power45:02

    Define radar cross-section and relate incident and reflected power to target properties. Analyze how transmitter power, pulse repetition, and target shape influence echo strength and unambiguous range.

Description

This course provides you to learning experience in the development of Radar equation for various conditions. It briefs on frequencies used for radar application. It proves the modification radar equation from basic to usable in the various application. This course differentiates the ambiguous and unambiguous range of radar. The basic building blocks of the radar is explained with suitable conditions, It consists radar transmitter and receiver. Radar transmitter and receivers elaborated in this course with various conditions. It explains the prediction of range performance at various condition. It explains the minimum detectable signal level required by the radar receivers. The signal received at radar receiver contains noise, to suppress the noise, apply the threshold level to remove noise. The noise removal process is discussed in this course. Receiver’s noise consideration for development of radar equations is discussed in the course. It shows the level of signal to noise ratio requirement for the detection of the echo signal received from the target. It provides understanding of false alarm time and probability of echo signal received at receiver from the target. It demonstrates the radar cross section from the echo signal received at radar receiver. It elaborates transmitter power requirement suitable for echo signal reception from the target at various angle. It shows the requirement of pulse repetition frequency for ambiguities in the signal reception at radar receiver. It elaborates the system loss at radar from various conditions. This course is helpful for understanding the radar basic and range equations.

Who this course is for:

  • Designer interested to develop radar system
  • Learner understand the concepts of Radar Cross Section.
