Uav ground penetrating radar array

A method performed by an electronics system associated with a first signal system having a radar antenna, the method comprising:

• receiving, via the radar antenna from a second signal system, a calibration receive signal corresponding to a calibration transmit signal transmitted by the second signal system via a radar antenna, the calibration receive signal being different from the calibration transmit signal based at least in part on degradation of the calibration transmit signal as it travels from the second signal system to the first signal system;
• identifying a transfer function that maps the calibration transmit signal to the calibration receive signal;
• identifying a pre-compensated transmit signal that when input to the transfer function outputs a desired receive signal;
• and
• transmitting, via the radar antenna to the second signal system, the pre-compensated transmit signal so that the second signal system can transmit the pre-compensated transmit signal via a radar antenna wherein a pre-compensated receive signal received via the radar antenna of the first signal system approximates the desired receive signal based at least in part on degradation of the pre-compensated transmit signal as it travels from the first signal system to the second signal system.

A first signal system interfacing with a radar transmitter and receiver pair, the first signal system comprising:

• a component that controls transmitting a first signal via the radar transmitter;
• a component that controls receiving a second signal via the radar receiver, the second signal corresponding to a degradation of the first signal during transmission;
• a component that controls identifying a transfer function that maps the first signal to the second signal and identifies a third signal when input to the transfer function outputs a fourth signal;
• and
• a component that controls transmitting the third signal via the transmitter so that the third signal is received as an approximation of the fourth signal based on degradation that is similar to the degradation of the first signal.
