ELEC-E4430 - Microwave Engineering II D, Lecture, 21.3.2022-2.6.2022

Osion kuvaus

• Final project
  In the last part of the course you design a Doppler radar. You have designed most parts/components of the radar circuit in the homework exercises. In the final project work you integrate those components and fine-tune them, and finally verify in AWR that the complete radar circuit operates as desired. The project work may be done either individually or in pairs. More instructions are found in the attachment below.

  You can get your own student license for AWR (only for Aalto students)!The AWR Desing Environment is available in both PC classes in the TUAS building (TU4&AS5), and in Maarintalo PC class "Maari-E". 
  

  

  Fig. Illustration of a possible radar circuit. The use of commercial amplifiers is optional e.g. if your oscillator power level is too low or the mixer conversion loss too high for a reasonable radar range. The ADC at the end of the green signal line is given (NI MyDAC), see its measured noise floor below.

    Final project presentation Tehtävä

    Saatavilla vasta, kun: You are a(n) Opiskelija

    Please upload your final presentation slides here. The overall assignment will be assessed during the final project seminar, i.e. through your seminar presentation (on MOnday, May, 30, 2022, starting at 10:15 in OIH A113, as usual). Everyone presents his or her own radar in 5 min.! Also, everyone acts as an ”opponent” for a fellow student once.

    For your radar range calculations, you can assume the receiver sensitivity at the detector (for the IF signal) to be around -110 dBm.

    Mini-Circuits' components Kansio

    For the radar circuit components that you cannot succeed to design, you can use (as a backup) commercially-available components from Mini-Circuits in the Doppler radar. The available components are: voltage-controlled oscillator (ZX95-2150VW), mixer (ZX05-C24LH), and there are also the low-noise amplifier (ZRL-3500) and broadband amplifier (ZX60-3018G+) that you may use in the final radar circuit. You find specs sheets of all these components in this folder (remember: you do not design the optional amplifiers in this course!).
