 The C-band, low-power, cross-section-measurement system in conjunction with two static range configurations was used for full-scale targets weighing up to 4,000 pounds rotated through 360 degrees.Since measurements must be made on targets as if they were located in free space, returns from other than the target were reduced to 10−5 m², the general background level of one tower-terrain combination.The low-power radar was capable of transmitting any linear, circular, or elliptical polarization at C-band frequencies.
