A passive radar system is inherently multi-static ... This allows us to perform deconvolution on the autocorrelation function of the received echo. This is something that is called lag-profile ...

Unlike active radar systems which use a specific radio source to look for reflections, this system is a passive radar system that uses radio waves already present in the environment to track objects.

LTCC-based passive integration accelerates RF design, offering compact, high-performance solutions for 5G, radar, and IoT with improved thermal and frequency stability.
