Referring to Fig. 1, it is a kind of schematic flow sheet of the methods of exhibiting of channel parameter disclosed in the present embodiment.Wherein, Fig. 1 Shown method can apply to channel parameter exhibiting device, and the device can apply to control terminal, and the control terminal can be with Including but not limited to remote control, video eyeglasses, smart mobile phone, tablet personal computer etc..As shown in figure 1, this method can include it is following Step：
101st, the frequency point sets for carrying out frequency point scanning according to preset time resolution ratio and predeterminated frequency resolution ratio and obtaining are obtained.
In the present embodiment, channel parameter exhibiting device can enter line frequency according to default temporal resolution and frequency resolution Spot scan obtains frequency point sets, can also carry out frequency point scanning according to default temporal resolution and frequency resolution by aircraft Frequency point sets are obtained, and are sent to channel parameter exhibiting device, the present embodiment does not limit.
Specifically, can carry out frequency point scanning in frequency range can be used, be selected such as citizens' radio band or in user Frequency range in carry out frequency point scanning, so as to scan multiple frequencies, obtain frequency point sets.
Further, channel parameter exhibiting device can interactive interface display scan frequency point sets to user, the friendship Mutual interface is as shown in Figure 3.
Swept it is understood that channel parameter exhibiting device carries out frequency on time component according to certain time interval Retouch, a frequency is determined at interval of certain frequency in frequency component, so as to obtain frequency point sets.
As a kind of feasible embodiment, channel parameter exhibiting device is being obtained according to preset time resolution ratio and preset Before frequency resolution carries out the frequency point sets that frequency point scanning obtains, following operation can also carry out：
The positional information for being presently in position is obtained, and determines that being presently in position allows what is used according to the positional information Frequency range.
Accordingly, channel parameter exhibiting device obtains carries out frequency according to preset time resolution ratio and predeterminated frequency resolution ratio Scanning the concrete mode of obtained frequency point sets can be：
Obtain what is obtained according to preset time resolution ratio and predeterminated frequency resolution ratio in the enterprising line frequency spot scan of above-mentioned frequency range Frequency point sets.
