Abstract. The method of
preliminary processing of the LFM signal in the radar complex RLC-L for the
spacecraft «Luna-Resurs-1» is considered. The illustration of this method is
represented.
It is shown that the radar resolution ability of RLC-L radar complex
with a preliminary processing based on the quadrature phase detector of the LFM
signal, is determined only by the signal tuning bandwidth. The calculation of resolution ability has been carried out for the radar complex RLC-L (for the «Radar-20» and
«Radar-200»).
A method for increasing the resolving ability of a radar by increasing
the number of cycles of frequency variation for the same period T is proposed. Conclusions: the resolving ability will increase in direct proportion to the number of cycles of frequency
variation for the same period T.
The limitation of the number of cycles of frequency tuning in the
transmitting channel of the radar can be only the limitations in the capabilities
of the equipment for fast and accurate linear frequency tuning and the increase
in the influence on the width of the spectrum of the output signal of
intermediate intervals between the tuning cycles.
Keywords:
