Although WiFi signal based range-Doppler -the wall imaging, and object localization have been well addressed in the last decade [5-9], we show some different considerations specific to sub-surface target mapping. Bookmark this article. The system uses an interferometer antenna and cross-correlation techniques to measure the time delay in receiving a reflected signal from the target as compared to receiving a direct signal from the signal source. Compared with monostatic SAR imaging, bistatic SAR acquires the echo signal of targets from various directions, in the sense of scattering preference and technical feasibility, to gain advantages by extending limited one-dimensional backscattering to two-dimensional bistatic data, expanding the dynamic range of received signal, and decoupling complex electromagnetic wave-target interactions. over 18 million articles from more than The objective of this effort is to develop interference mitigation algorithms for bistatic space-based radar (SBR) systems. A bistatic reader has two separate RF channels for transmitting and receiving RF energy for every port (see figure 2 below).

Bistatic radar • bistatic radar has potential advantages in detection of targets which are shaped to scatter energy in directions away from the monostatic; • the receiver is covert and therefore safer in many situations; • countermeasures are difficult to deploy against bistatic radar; The transmitter and receiver positions of a bistatic radar are highly influential on its performance in radar target identification since the radar cross-section of a target varies with these positions.
