Compensating for frequency fluctuation in directional systems

A computer program product comprising computer executable program code recorded on a computer readable medium, comprising:

• computer program code configured to activate a signal measurement operation in an apparatus;
• computer program code configured to measure signal response in an antenna system comprising two or more antennas, wherein the signal response is measured in accordance with a pattern;
• computer program code configured to, after completing at least one measurement of the antenna system, alter the pattern to change the manner in which the antenna system is measured;
• computer program code configured to measure signal response in the antenna system in accordance with the altered pattern;
• computer program code configured to average the signal response measured for the antenna system in the pattern with the signal response measured for the antenna system in the altered pattern;
• and
• computer program code configured to provide the results of the averaging to another system in the apparatus.

An apparatus, comprising:

• a processor, the processor being configured to:
• activate a signal measurement operation;
• measure signal response in an antenna system comprising two or more antennas, wherein the signal response is measured in accordance with a pattern;
• after completing at least one measurement of the antenna system, alter the pattern to change the manner in which the antenna system is measured;
• measure signal response in the antenna system in accordance with the altered pattern;
• average the signal response measured for the antenna system in the pattern with the signal response measured for the antenna system in the altered pattern;
• and
• provide the results of the averaging to another system in the apparatus.

An apparatus, comprising:

• means for activating a signal measurement operation in the apparatus;
• means for measuring signal response in an antenna system comprising two or more antennas, wherein the signal response is measured in accordance with a pattern;
• means for, after completing at least one measurement of the antenna system, altering the pattern to change the manner in which the antenna system is measured;
• means for measuring signal response in the antenna system in accordance with the altered pattern;
• means for averaging the signal response measured for the antenna system in the pattern with the signal response measured for the antenna system in the altered pattern;
• and
• means for providing the results of the averaging to another system in the apparatus.

A system, comprising:

• an apparatus;
• and
• a signal source;
• the apparatus activating a signal measurement operation that measures the response in an antenna system comprising two or more antennas to a signal emitted by the signal source, wherein the signal response is measured in accordance with a pattern;
• after completing at least one measurement of the antenna system, the apparatus further altering the pattern to change the manner in which the antenna system is measured and measuring the response in the antenna system to the signal emitted by the signal source in accordance with the altered pattern;
• and
• the apparatus further averaging the signal response measured for the antenna system in the pattern with the signal response measured for the antenna system in the altered pattern and determining the direction of the signal source based on the average.
