QUANTITATIVE MEASUREMENTS OF RADAR ECHOES FROM AIRCRAFT XIV. FJ-2
Abstract
Some radar characteristics of the FJ-2 aircraft are described quantitatively for radar frequencies of 115, 215, 1250 and 2813 Mc. The radar area is greater at the lower frequencies (115 and 215 Mc) than at the higher frequencies (1250 and 2813 Mc). Radar areas at 115 Mc tend to be six times as great, and radar areas at 215 Mc tend to be three times as great, as the radar areas at the two higher frequencies. Average values of the radar area over both head and tail aspects are found to be: 115 Mc - 10.0 sq m; 215 Mc - 3.2 sq m; 1250 Mc - 1.7 sq m; 2813 Mc - 1.7 sq m. The probability distributions of single-pulse amplitudes are essentially equal to the probability distributions of median-pulse amplitudes when such medians are obtained from sample times of 8 seconds for 115 Mc, 1/2 second for 215 Mc and 1/12 second for 1250 and 2813 Mc. A comparison between these measurements and model measurements is attempted. (Author)
