Claim:
1. A radar array comprising: a panel, the panel comprising a top side and a bottom side; a plurality of high-frequency antennas coupled into a high-frequency array coupled to the panel; at least one low-frequency resistive vee dipole transmitting antenna; and at least one low-frequency resistive vee dipole receiving antenna; wherein the at least one low-frequency resistive vee dipole transmitting antenna and the at least one low-frequency resistive vee dipole receiving antenna are coupled into a low-frequency array, the low-frequency array being disposed on the panel; wherein at least one of the plurality of high-frequency antennas is a high-frequency transmitting antenna operable to transmit a first signal having a first center frequency; wherein the at least one low-frequency resistive vee dipole transmitting antenna is operable to transmit a second signal having a lower center frequency than the first center frequency; wherein the first center frequency has a value exceeding approximately 500 MHz; wherein the lower center frequency has a value between approximately 50 MHz and approximately 500 MHz; and wherein the at least one low-frequency resistive vee dipole transmitting antenna is configured to transmit electromagnetic waves in a direction orthogonal to the electromagnetic waves transmitted by each high-frequency antenna.
