超短波及L波段航空信道通信模型，分为停放、滑行、起降及飞行场景，受载频、飞行速率、时延、数据率及波束到达角影响。(Aeronautical channel model of VHF and L band, which is classified into parking, taxi, take-off and arrival, and en-route scenarios, and is affedted by the carrier frequency, velocity, delay, data rate and arrival angle of the beams.)

region growing: Perform segmentation by region grow1ng. [G, NR, SI, TI] = REGIONGROW(F, SR, T). Scan be an array (the same size as F) with a 1 at the coord1nates of every seed point and 0s elsewhere. S can also be a single seed value. Similarly, T can be an array (the same size as F) containing a threshold value for each pixel in F. T can also be a scalar, in wh1ch case it becomes a global threshold.
