The 3D radar "Quasar" has a viewing range of 6 to 290 km for ground targets and up to 400 km for low-flying targets when placed on a lifting platform up to 5 km high. It has a maximum range resolution of 5 meters and height resolution of 300 meters, with azimuth and elevation resolution of 2 degrees. The radar weighs up to 100 kg including a thermal regulation system, uses FM and PM signals, and can be combined with identification equipment.

1. When placed on a platform with a lifting height of up to 5 km, the radar's viewing
area will be from 6 to 290 km for ground aims, up to 400 km for low-flying aims.
With a permitted bandwidth of the probing pulse of 200 MHz (from 1.2 to 1.4 GHz),
the maximum resolution in range will be 5 meters, in height – 300 m. The azimuth and
elevation resolution is 2°; the speed is 2 m/s.
The maximum power consumption will be 2.5 kW – consumption can be optimized by
selecting the viewing area and the radar operating mode.
The weight of the radar with a thermal regime system is up to 100 kg.
The type of signal used during sensing is FM, PM.
It can be combined with radar identification equipment.
Compensation for changes in the angular position of the balloon: accounting for the
angular position of the balloon when constructing a radar image using information from
angle sensors mounted on the balloon body (accuracy up to 0.05 ° with a base between
sensors from 7 m) or gyrostabilized platform (additional weight - up to 29 kg).

3. Principles of digital signal processing
As part of the observation cycle, the following is performed:
 generation of code sequences of probing pulses from the FM / PM and
transmission of these sequences to the DAC for the formation of analog signals
with variable parameters (bandwidth, center frequency, pulse duration, signal
response reception zones);
 reading of primary data - digitized reflected signals from the ADC output;
 range compression of primary data – processing of recorded reflected signals by
correlation analysis methods in the time domain;
 saving the results in the built-in memory of the SoC for subsequent transfer to an
external storage device.
These operations are performed in the built-in information processing modules implemented
on the FPGA, with a processing clock frequency of at least 100 MHz
We have received two patents:
 Patent for a utility model "Device for determining parameters of radio signals";
 Patent for a utility model "Device for constructing a radar image using a radar station with
a synthesized aperture".
