First Claim
1. A device, comprising:
- a radar system configured to be placed in a hiding mechanism, the radar system comprising;
one or more transmit antennas oriented within the hiding mechanism and configured to transmit one or more radar signals toward a barrier, the one or more radar signals comprising one or more frequencies that penetrate through the hiding mechanism and through the barrier, the barrier having a first side located at a stand-off distance from the hiding mechanism and a second side opposite to the first side;
one or more receive antennas oriented within the hiding mechanism and configured to receive reflection signals of the transmitted radar signal back through the barrier and back through the hiding mechanism, the received reflection signals resulting from the one or more radar signals transmitted though the barrier interacting with one or more individuals located at the second side of the barrier;
one or more transceivers coupled to the one or more transmit antennas and the one or more receive antennas, the one or more transceivers adapted to generate the radar signals and process the received reflection signals; and
an electronic processor coupled to an electronic storage, the electronic storage comprising instructions, that when executed, cause the processor to;
analyze the received reflection signals of the transmitted one or more radar signals; and
determine, based on the analyzed received reflection signals, locations of the one or more individuals within a region at the second side of the barrier.

12. A device, comprising:
-
a sensor system comprising; one or more transmit antennas configured to transmit one or more radar signals, the one or more radar signals comprising one or more frequencies that penetrate through a barrier, the barrier having a first side located at a stand-off distance from the one or more transmit antennas and a second side opposite to the first side; one or more receive antennas configured to receive reflection signals of the transmitted one or more radar signals received back through the barrier, the reflection signals resulting from the one or more radar signals transmitted through the barrier interacting with one or more objects located at the second side of the barrier and within a field of view of the one or more receive antennas; one or more transceivers coupled to the one or more transmit antennas and the one or more receive antennas, the one or more transceivers adapted to generate the one or more radar signals and process the received reflection signals of the transmitted one or more radar signals; and an electronic processor configured to determine, based on data corresponding to the received reflection signals of the transmitted one or more radar signals, locations of the one or more objects within a region at the second side of the barrier. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method comprising:
-
accessing, at a processing system, a multi-frequency radar signal, the multi-frequency radar signal including a plurality of frequencies; generating, at the processing system, a distance range profile based on the accessed multi-frequency radar signal; identifying, at the processing system, a target in the generated range profile; determining, at the processing system, a distance range to the identified target; generating, at the processing system, filtered multi-frequency radar signal data that includes the identified target; extracting, at the processing system, a Doppler-induced phase of the target at the plurality of frequencies; and determining, at the processing system, a Doppler-induced phase of the target at a single frequency based on the extracted Doppler-induced phase of the target at the plurality of frequencies. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
