Abstract. This
paper is devoted to the experimental research of using a wideband radar
measuring set based on a vector network analyzer in order to provide radar
cross section measurements and inverse synthetic aperture imaging in
semi-naturals and naturals conditions. Modern vector network analyzers provides
wideband measurements at the range 10 Mhz ... 67 Ghz in continuous and pulse
modes with up to 32000 fixed frequency points. Electronic calibration module
allows low error of magnitude (0.01 dB) and phase (0.1º) measurements with high
dynamic range (up to 130 dBm) and noise level which does not exceed -120 dBm. Vector
network analyzer has integrated operational system and obtain user to control
experiment in real time. All this makes it possible to create a compact movable
wideband radar measuring set based on VNA with the necessary options. The analyzer
and control computer are located in a mobile cabin with power generator. Two parabolic
antennas (transceiver 2.4 meters diameter and receiver 1.2 meters diameter) are
mounting on the roof of the cabin. Each of the antennas is equipped with the twin-polarized
horn irradiator KIR 5800 DR, which operates at the frequency 4.5…7.5 GHz. The Dahua
SD6AL240-HNI camera is mounting between two antennas for monitoring the object
during an experiment time. The unmanned aerial vehicle is used to check antennas
directional diagram. As the result, we define requirements and give recommendations
of the radar measuring set parameters, and also propose a method of the
experiment with an object moving along an arbitrary trajectory.
Key
words: radar
measuring set, vector network analyzer, radar cross section, inverse synthetic
aperture, radar images.
