Radiation testing system for digital television station transmitting power under city environment

The invention relates to a radiation testing system for digital television station transmitting power under a city environment, and belongs to the field of radio transmission system performance index testing. The radiation testing system comprises a directional receiving antenna, power measuring equipment, a distance measuring and positioning device and a control device. The directional receiving antenna receives electromagnetic waves emitted by a digital television station, converts the electromagnetic waves into electric signals, and transmits the electric signals to the power measuring equipment. The power measuring equipment calculates the channel power Pr which is incident to the receiving antenna according to the electric signals. The distance measuring and positioning device measures the distance L between the receiving antenna and a transmitting antenna. The control device comprises an equivalent omnidirectional radiation power estimation module, and the equivalent omnidirectional ...
