1. A method for dynamically modifying a sampling operation of a sensor, the method comprising:
obtaining a dynamically changing transmission characteristic based on an available channel bandwidth parameter, the dynamically changing transmission characteristic comprising at least one of a sample rate, a time period, or a spectral bandwidth;
updating the sampling operation of the sensor based on the dynamically changing transmission characteristic;
measuring signal energy at a location of the sensor;
sampling the signal energy using the sampling operation to obtain sampled data;
providing the sampled data to a processing entity configured to analyze the data using a dynamically updated cross-ambiguity function;
wherein when the dynamically changing transmission characteristic includes a second sample rate, updating the sampling operation includes changing a first sample rate of the sampling operation to be the second sample rate;
wherein when the dynamically changing transmission characteristic includes a second time period, updating the sampling operation includes changing a first time period of the sampling operation to be the second time period; and
wherein when the dynamically changing transmission characteristic includes a second spectral bandwidth, updating the sampling operation includes changing a first spectral bandwidth of the sampling operation to be the second spectral bandwidth.
