Background technology
TACAN is a kind of polar coordinates radio navigation system of short range, and can complete the azimuth with respect to aircraft and the measure of distance to earth station；TACAN is a kind of Navigation Equipment being widely used, and it is widely used in the formation of aviation warship, navigation Service can be provided for the ship-board aircraft of aircraft carrier, therefore, the detecing of TACAN signals is received and treatment is an important directions of electronic reconnaissance, and tool is of great significance.
With the development of digitlization process, traditional TACAN equipment is also introduced into digitized thought, TACAN Digital Signal Processing modes are that the signal that receiver is received is amplified to intermediate frequency by frequency conversion, then data signal is produced to be processed by analog to digital conversion, conventional method is because being limited to hardware technology, using a rationally relatively low conversion frequency, TACAN ranging devices are that the time punctuate of the relatively-stationary amplitude point of pulse signals enters the measurement of row distance and angle, so as to influence the precision of test to a certain extent；Simultaneously because severe and multipath signal the interference of outfield electromagnetic environment, makes pulse signal waveform produce serious deformation, the identification to pulse to generate very big difficulty.
The content of the invention
The purpose of the present invention is the problem for overcoming the pulse signal wave deformation that occurs in pulse signal identification process present in prior art, pulse recognition relatively difficult.
For this, the invention provides a kind of TACAN pulsing signal recognition devices, including pending data, wherein, also circuit, thresholding circuit, rising edge identification circuit, trailing edge identification circuit, pulse confirmation circuit, peak extraction circuit, peak value moment expanded circuit, particular point is preserved including time delay to demarcate；The pending data preserves circuit and is connected with the time delay, and the time delay preserves circuit and is connected with the peak value moment expanded circuit；The pending data is also connected with the thresholding circuit, and the thresholding circuit, the rising edge identification circuit, the trailing edge identification circuit, the pulse confirm that circuit, the peak extraction circuit, the peak value moment expanded circuit, the particular point are demarcated and be sequentially connected.
A kind of above-mentioned TACAN pulsing signal recognition devices, the pending data is the data signal after bandpass filter, quadrature demodulator, smoothing filter are demodulated treatment.
A kind of above-mentioned TACAN pulsing signal recognition devices, the pulse confirms that circuit confirms whether pulse reaches by pulse width pulse signals.
Beneficial effects of the present invention：This TACAN pulsing signal recognition devices that the present invention is provided, by increasing the design of thresholding circuit, after a rational threshold values high is set, realize the purpose for removing the low-noise signal in signal；By setting the design of relatively loose rising edge and trailing edge identification circuit, having reached pulse signals carries out the effect of further denoising；The design of circuit is confirmed by increasing pulse, the effect for confirming whether pulse reaches furthermore achieved that by characteristics such as pulse widths；Extract maximum and the moment of pulse, the width for analyzing pulse further extracts pulse data in delay data, then some specific amplitude values are extracted, so as to reduce to the misrecognition of pulse or leakage identification, it also avoid some especially determine the identification of 3% and 5% amplitude point less than problem；The TACAN pulsing signal recognition devices, accuracy is high, recognition speed is fast to have the advantages that identification, and application prospect is extensive.
The present invention is described in further details below with reference to drawings and Examples.
