Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Real-time spectrum analyzers and existing modulation domain analyzers have insufficient measurement bandwidth, and broadband frequency hopping signal measurement cannot be performed. The measurement cost of the oscilloscope method is high, and the price of a 30GHz bandwidth oscilloscope is generally more than 1 million yuan. The invention provides a low-cost broadband Frequency hopping signal measuring circuit and method.

[0042] The invention provides a ti...

Abstract

The invention proposes a time-frequency measurement circuit for broadband frequency hopping signals, including: a power distribution unit, a peak power detection unit, a power adjustment unit, a broadband frequency division unit, a counting unit without dead zone, a frequency calculation unit and a display unit. The time frequency measurement circuit of the broadband frequency hopping signal of the present invention can quickly measure the frequency of the broadband frequency hopping signal as a function of time, and is used to measure the frequency hopping dwell time, frequency hopping pattern, etc. The present invention uses a broadband frequency division method for measurement, It is economical and applicable, and the cost is only 1 / 5 or lower than that of an oscilloscope.

Description

technical field [0001] The invention relates to the field of electronic measurement, in particular to a time-frequency measurement circuit for broadband frequency-hopping signals, and also to a time-frequency measurement method for broadband frequency-hopping signals. Background technique [0002] With the rapid development of frequency hopping speed in signal generation technology, frequency hopping technology has been more and more widely used in the communication field due to its unique anti-monitoring and anti-jamming capabilities, and has become the development trend of confidential communication and communication countermeasure technology. [0003] The frequency range covered by frequency hopping communication is getting wider and wider, up to several GHz. In order to improve the anti-interference ability, frequency-agile radar also adopts the local oscillator frequency hopping method. The frequency hopping range can reach more than 10GHz. The frequency of agile frequen...
