Abstract
Sandwich Wire Antenna Arrays are attractive for its light-weight and low-cost attributes. However, this class of antennas have not been used in radar systems due to its moderate power handling capabilty and a lack of satisfactory design procedures for low-sidelobe applications. Recently, there has been interest in employing the Sandwich Wire Antenna in surveillance radar system on small naval vessels. Design studies for sandwich wire antennas have been undertaken. Being a travelling wave antenna, the main beam of this antenna possesses a frequency dependent squint. There is concern that this squint may have adverse effect on the signal processing system designed for radar systems employing conventional antennas. In this report, a feasibility study is carried out to evaluate the effects of the frequency squint on existing radar signal processing performance. In addition, new modes of operation designed to exploit the frequency squint are also identified and evaluated.
