Measuring device and method for projectile flying speed and trajectory

The invention relates to a measuring device for a projectile flying speed and trajectory. At least one linear array plane unit is included; each linear array plane unit comprises two pressure sensor linear array sets arranged in the same plane; each pressure sensor linear array set comprises a first linear array and a second linear array which are arranged in parallel in a spaced manner; each first linear array and each second linear array are each a sensor linear array composed of a plurality of pressure sensors arranged along the same straight line at equal intervals; the length of each first linear array is smaller than that of the corresponding second linear array, and the two end positions of each first linear array do not exceed the end portions of the corresponding second linear array; the two pressure sensor linear array sets are arranged oppositely in parallel; and the first linear arrays are located on the inner side, and the second linear arrays are located on the outer side.
