Time-based correction technique for multistatic radar system

A non-transitory computer-readable medium storing machine instructions which, when executed by at least one processor, cause the at least one processor to:

• determine a first clock offset α1 and a first initial time offset τinitial;1 between a first clock signal for a first radar transceiver and a reference clock for the at least one processor;
• determine a first clock drift for the first clock signal relative to the reference clock based on the first clock offset α1 and the first initial time offset τinitial;1;
• determine a second clock offset α2 and a second initial time offset τinitial;2 between a second clock signal for a second radar transceiver and the reference clock;
• determine a second clock drift for the second clock signal relative to the reference clock based on the second clock offset α2 and the second initial time offset τinitial;2;
• and
• compensate for the first and second clock drift by applying the first clock drift to transmitted or received radar signals of the first radar transceiver and the second clock drift to transmitted or received radar signals of the second radar transceiver.
