Problems solved by technology

High-amplified radios are more sensitive and powerful than direct-detection radios, but have poorer selectivity and more complicated tuning
To amplify the high-frequency signal received from the antenna by hundreds or even tens of thousands of times, generally several levels of high-frequency amplification are required, and each level of circuit has a resonant circuit. When the received frequency changes, the resonant circuit must be rebuilt. Adjustment, and it is difficult to ensure that the selectivity and passband are exactly the same after each adjustment. In order to overcome these shortcomings, almost all current radios use superheterodyne circuits

Abstract

The invention relates to a monitoring type radio data storage method. The method comprises the following steps: a first processing device is used for connection with a spherical camera for receiving afull-angle image, the full-range image is averagely segmented into blocks in sizes of corresponding blocks on the basis of the distance from the average brightness of the full-range image to a presetbrightness scope center value, for each block, based on a pixel value variance of the block, corresponding affine transformations with different strengths are selected so that affine transformation blocks are obtained, and the obtained affine transformation blocks are spliced so that an affine processed image is obtained.

Description

technical field [0001] The invention relates to the field of radios, in particular to a monitoring radio data storage method. Background technique [0002] The simplest radio is called a direct detector. However, the high-frequency radio signal obtained from the receiving antenna is generally very weak, and it is not suitable to send it directly to the detector. It is better to insert a high-frequency amplifier between the selection circuit and the detector to amplify the high-frequency signal. Even if a high-frequency amplifier has been added, the power of the detection output is usually only a few milliwatts, which is okay to listen to with headphones, but it is too small to use a speaker, so an audio amplifier is added after the detection output to drive the speaker. High-amplitude radios have higher sensitivity and higher power than direct-detection radios, but they are less selective and more complicated to tune. To amplify the high-frequency signal received from the...
