"Sandwich Wire Antenna Arrays are attractive for their light-weight and low-cost. However, this class of antennas has not been used in radar systems because of its moderate power handling capability 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 systems on small naval vessels. Design studies for sandwich wire antennas have been undertaken through industrial contracts. Being a travelling wave antenna, it produces a main beam with 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 identified and evaluated"--Abstract, page 1. Issued also in print format. Microwave antennas. Surveillance radar.
