Patent ID: 8477065

Claim:
An antenna system comprising: a first unit configured to receive HF or VHF radar signals, the first unit including: a first loopstick antenna including a first phase center and a first loopstick axis; and a second loopstick antenna including a second phase center and a second loopstick axis that is substantially orthogonal to the first loopstick axis; a second unit configured to transmit and receive HF or VHF radar signals, the second unit including: a first antenna including a third phase center, wherein the third phase center, the first phase center, and the second phase center are substantially collinear, the first antenna further including a first axis that is substantially orthogonal to the first loopstick axis and to the second loopstick axis; and a receiver module coupled to the first unit and to the second unit, the receiver module being configured to: receive a first receiver input signal from the first unit; receive a second receiver input signal from the second unit; and output a receiver output signal to the second unit.
