<p>Four wheeled vehicle supporting a ground probing radar antenna (52) has an aluminium alloy square plate (10) and four wheel mountings (14) supported by four pairs of equal-length arms (18, 20). The arms as seen in plan are arranged in a square. One arm (18) in any pair extends lengthwise of the vehicle from an anchorage (30) on the vehicle to a mounting (14) and the other (20) extends transversely of the vehicle from an anchorage (32) on the vehicle to the mounting (14). Each mounting carries a buffer (36) which on upward movement presses against one of two spring arms (38) carried by mountings (42), one arm being locked in its mounting. The vehicle has an overcover (70) and an undercover (72). In a modification pneumatic spring units instead of arms (38) control vertical wheel motion.</p> |
