Abstract

The invention relates to the technical field of computer data processing, in particular to a radio frequency signal detecting and positioning method, which comprises the following steps of: firstly, calibrating gain responses of a receiver at different attenuation gears in a full frequency band so as to enable a receiving power value of the receiver to be equal to a power value of a transmitting power value after rated gain amplification; equally dividing the bandwidth into narrow-band signals, performing FFT on the narrow-band signals, and performing gain compensation on the obtained frequency spectrum; further solving a target frequency and a primary power value of a to-be-measured signal in the bandwidth, and determining a final frequency and a final power value of the to-be-measured signal. According to the method, the frequency and the power of the signals of any order and any frequency band in the bandwidth can be detected and positioned.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a radio frequency signal detection and positioning method. Background technique [0002] In the field of radio frequency testing, especially in the field of communication and in the design of phase-locked loops, it is very important to test useful signals and spurious signals. In the field of communication, spurs outside the occupied frequency band will occupy other communication channels and cause damage to other channel signals. Interference reduces the sensitivity of other channels, and the frequency offset and power offset of the useful signal will also affect the quality of the channel signal; therefore, it is of great significance to accurately test the signal. [0003] In radio frequency testing, in order to accurately detect and locate the signal, it is necessary to detect and locate the frequency and power of any order and any frequency band signal withi...
