DETERMINING PENETRABILITY OF A BARRIER
First Claim
Patent Images
1. A system comprising:
- a transceiver configured to receive and transmit multiple radar signals, each radar signal associated with a frequency that nominally penetrates a barrier;
a processor coupled to an electronic storage, the electronic storage storing instructions that, when executed, cause the processor to perform operations comprising;
sensing a portion of a signal transmitted by the transceiver; and
analyzing the sensed portion of the signal to determine a penetrability of a barrier; and
an output configured to present a perceivable indicator related to the determined penetrability of the barrier.

Abstract
A through-wall radar system includes a transceiver configured to receive and transmit multiple radar signals, each radar signal associated with a frequency that nominally passes through a barrier. The system includes a processor coupled to an electronic storage, the processor configured to sense a portion of a signal transmitted by the transceiver and analyze the sensed portion of the signal to determine a penetrability of a barrier. The system also includes an output configured to present a perceivable indicator related to the determined penetrability of the barrier.

7. A method comprising:
-
accessing first data comprising a sensed portion of a signal received by a radar transceiver operating in free space; accessing second data comprising a sensed portion of a signal received by the radar transceiver operating close to a barrier; determining a first leakage signal from the first data; determining a second leakage signal from the second data; comparing the first leakage signal and the second leakage signal; determining a penetrability of the barrier based on the comparison; and presenting the penetrability of the barrier. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
accessing first data comprising a sensed portion of a signal received by a radar transceiver operating in free space; accessing second data comprising a sensed portion of a signal received by the radar transceiver operating close to a barrier; determining a first leakage signal from the first data; determining a second leakage signal from the second data; comparing the first leakage signal and the second leakage signal; determining whether signals transmitted from the transceiver pass through the barrier based on the comparison; if the signals are determined to not pass through the barrier, presenting a first perceivable indicator; and if the signals are determined to pass through the barrier, presenting a second perceivable indicator that is distinguishable from the first perceivable indicator. - View Dependent Claims (18, 19)
