Digital sounding-pulse generator for UHF MST radar

Abstract

A prototype of the sounding-pulse generator unit for mesosphere-stratosphere-troposphere ultra-high frequency radar (MST radar) has been developed. The pulse generator has the following technical specifications: the output frequency range of 40-60 MHz; the output power not lower than 1 W; the RF pulse length from 0.1 to 50 μs; the interpulse interval from 2 μs to 60 μs. The RF pulse envelope can be of different shape: rectangular, trapezoidal, Gaussian etc. The RF pulse bursts can also be generated with the phase modulation using the Barker code or other codes.
