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 4.57.5 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.
