Abstract: The sky is scanned with transmitted radar pulse beam of electromagnetic radiation from a high gain antenna with a narrow viewing angle. Weather echos from the radar pulse are monitored with a low gain receiving antenna that has a wide, or moderate, viewing angle of the sky. The source location of echo signals along the direction of the radar pulse beam path are defined by synchronizing the sampling of the echo signal at the receiving station with the transmission of radar pulses at the transmitting station. The receiving station defines the location of an echo signal source by knowing the locations of the transmitting and receiving antennas, the pointing angle of the transmitted beam and the relative time between transmission of the radar pulse and receipt of each echo signal sample along the transmitted beam path. The relative time can be defined by synchronizing the sampling of the echo signal with each transmitted pulse.

Abstract: A multiple-Doppler radar network can be constructed using only one, traditional, transmitting pencil-beam radar and one or more passive, non-transmitting receiving sites. Radiation scattered from the pencil beam of the transmitting radar as it penetrates weather targets can be detected at the receive-only sites as well as at the transmitter. In a bistatic system, the location of targets in Cartesian space can be calculated from the pointing angle of the transmitting antenna and the time between transmission of a radar pulse from the transmitter and detection at a passive receiver site.
