  1. 1. Miniaturization of a Low Power Harmonic Radar for UAV use

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Saleh Aljaser; [2019]
    Nyckelord :Harmonic; Radar; Insects; Tracking; Detection; UAV; FMCW; Small; Low Power; Wireless; Communications; Technology and Engineering;

    Sammanfattning : The aim with this Master thesis work is to design, build and test a small size, light weight and low power consumption harmonic radar system that will be installed in a flying drone for the purpose of tracking and localizing tagged Bogong moths near their aestivation caves and crevices in Australia during summer. A FMCW harmonic radar is proposed, it comprises a radar transmitter, receiver and a signal processor. LÄS MER

  4. 3. Ground-living predators of the apple fruit moth Argyresthia conjugella (Zell.)

    L3-uppsats, SLU/Dept. of Entomology

    Författare :Sara Furenhed; [2006]
    Nyckelord :ground-living predators; apple fruit moth; Argyresthia conjugella; mortality during hibernation; mesh exclusion cage; GLIMMIX; feeding test;

    Sammanfattning : Field studies were conducted in two orchards to investigate what type of ground- living predators that prey on the apple fruit moth during hibernation. Two tasks were addressed: 1) hibernation loss of the apple fruit moth was quantified, and 2) effect of the different predator groups were identified. LÄS MER
