摘要： A system and method for detecting targets with radar signals are disclosed which include a receiver configured to receive a radar signal on orthogonally-polarized channels and generate a receiver return vector from the received radar signal, a range filter configured to filter reflections in the receiver return vector at a selected range bin, and a polarization filter configured to filter an identified interference signal from a return of the range filter.

摘要： A system for improving resolution of frequency-dependent objects in radar contexts may include a radar device configured to transmit a radar signal and receive a return of the radar signal. In one example, the system may also include circuitry configured to generate a first data set representative of a range profile based at least in part on the return and/or generate a second data set representative of the range profile by applying at least one shift to the first data set. Additionally or alternatively, the circuitry may be further configured to characterize at least one frequency-dependent object detected in the range profile based at least in part on the first data set and the second data set. Various other apparatuses, systems, and methods are also disclosed.

摘要： A system and method for detecting targets with radar signals are disclosed which include a receiver configured to receive a radar signal and generate a first return vector having four elements representing four channels of a full-polarimetric radar reading, and a four-dimensional polarization filter applied to the first return vector, the four-dimensional polarization filter configured to arrange the first return vector in a column of four elements according to polarimetric components associated with of respective transmit/receive channels, take an inner product of a selected vector with the column, derive a projection coefficient by dividing the inner product by a magnitude of the selected vector, and produce an output by subtracting a product of the projection coefficient and the selected vector from the column.
