Abstract
A system includes an antenna array. The antenna array includes a plurality of antennas, wherein no two antennas of the plurality of antennas share a common y-coordinate or a common z-coordinate. The system includes a processor and a memory including computer program code. The memory and the computer program code are configured to cause the processor to receive signal data associated with a signal from the antenna array, generate a direction-finding (DF) result using a DF algorithm and the received signal data, and determine a location of a source of the signal using the generated DF result.
Claims20
A system comprising:
- an antenna array, the antenna array including a plurality of antennas, wherein no two antennas of the plurality of antennas share a common y-coordinate or a common z-coordinate;
- a processor;
- and
- a memory comprising computer program code, the memory and the computer program code configured to cause the processor to:
- receive signal data associated with a signal from the antenna array;
- generate a direction-finding (DF) result using a DF algorithm and the received signal data;
- and
- determine a location of a source of the signal using the generated DF result.
A computerized method comprising:
- receiving a signal using an antenna array, wherein the received signal is received from a region;
- generating a first direction-finding (DF) result using a DF algorithm and the received signal;
- projecting the received signal onto an axis to form a projected signal;
- generating a second DF result using the DF algorithm and the projected signal;
- combining the first DF result and the second DF result to form a combined DF result;
- and
- determining a location of a source of the received signal in the region using the combined DF result.
A computer storage medium has computer-executable instructions that, upon execution by a processor, cause the processor to at least:
- receive a signal using a diagonal antenna array, wherein the received signal is received from a region, wherein the diagonal antenna array includes a plurality of antennas and no two antennas of the plurality of antennas overlap on a first axis, wherein no two antennas of the plurality of antennas overlap on a second axis;
- generate a first direction-finding (DF) result using a DF algorithm and the received signal;
- project the received signal onto the first axis to form a projected signal;
- generate a second DF result using the DF algorithm and the projected signal;
- combine the first DF result and the second DF result to form a combined DF result;
- and
- determine a location of a source of the received signal in the region using the combined DF result.
