QUANTITATIVE MEASUREMENTS OF RADAR ECHOES FROM AIRCRAFT. XIII. F2H-2B
Abstract
The radar target characteristics (radar area) of the F2H-2B 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 (2813 and 1250 Mc.). With large samples of azimuth aspect and with equal weights given to equal aspect intervals, the average radar area at 115 Mc. is about six times greater than the average radar area at 2813 Mc. The probability that the radar area corresponding to a particular aircraft aspect will lie in a given 1 db interval is normally distributed. Over a wide range of aspects, the probability distribution of single pulse amplitudes is essentially equal to the distribution of median pulse amplitudes, where the medians are obtained from samples of length 1/12 second (for 2813 and 1250 Mc.), 1/2 second (for 215 Mc.), and 8 seconds (for 115 Mc.). The radar area for the two lower frequencies is given as a continuous function of aircraft aspect while the data for the two higher frequencies are given in the form of probability distributions.
