The utility model is described in further detail below.

Embodiment: see Fig. 1, a kind of shortwave multichannel monitoring radio receiver monitor, comprise short-wave receiver, system control server, broadband monitoring terminal and audio monitoring terminal, described short-wave receiver is connected with system control server, broadband monitoring terminal, the audio monitoring terminal signal of telecommunication, described short-wave receiver comprises short-wave radio frequency module, acquisition process plate, intermediate frequency process plate, network board and reference source input module, described short-wave radio frequency module, acquisition process plate, intermediate frequency process plate, is electrically connected between network board and reference source input module.Carry internal reference source, unit daily use can be met.But when the external reference source having the performances such as accuracy, stability, phase noise higher, also can access external reference source input, the at this moment automatic breaking inner reference source of equipment, be switched to external reference source input.Multiple monitoring work seat supported by short-wave receiver, and each monitoring work seat can process 4 road narrow band signals simultaneously, carries out optimum configurations, result display.

Described short-wave receiver has the radio-frequency front-end of two-way independent tuning, the I/Q data of exportable two-way 10MHz bandwidth signal and the ITUIQ data of 1 road adaptive-bandwidth bandwidth, there are two independently tuners, each tuner bandwidth of operation 10MHz, therefore instantaneous wideband is 20MHz, 129 arrowband, the road DDC data that short-wave receiver can export in this 20MHz bandwidth, and carry out demodulation and monitoring, can be used for the control of system to signal to keep, the signal control be particularly suitable for when signal is more crowded in instant bandwidth is kept.Can real-time reception 129 tunnel narrow-band reception channel data, support the multiple storage modes such as circulation, scheduling, prerecord, narrow-band filtering leaches a part of frequency band in being treated with lenience and being with, and the sample rate of minimizing tracer signal, to improve its registering capacity.

Audio monitoring terminal is installed on shortwave audio monitoring work seat computer, mainly carries out short-wave receiver narrowband operation state modulator, and can monitor simultaneously and show four road signal processing results.

Clock module, control command parsing module, adc data DDR receiver module is integrated with, broadband DDC module, ITUDDC module, ADC energy detection module, ADC parameter configuration module, DDC digital jointing output module in described acquisition process plate.Broadband receiver is dynamically one of most important index of whole receiver, it reflects the ability that receiver receives large-signal and small-signal simultaneously, because broadband receiver almost invariably receives many signals simultaneously, in large-signal environment, therefore detect that the ability of small-signal is with regard to particular importance.ADC dynamic particular importance in broadband receiver, in order to carry out direct radio frequency employing, receiver is just higher to the requirement of AD variator, and the particularly dynamic range of AD, directly affects the performance of receiver.Therefore we are on the basis meeting sample frequency, and we should select the A/D chip of seniority top digit as far as possible.

Mainly can weigh with two indices with the closely-related ADC dynamic property of receiver dynamic property: SFDR and TwoToneIMD.

SFDR Spurious-Free Dynamic Range (SpuriousFreeDynamicRange) refers to the effective value of signal amplitude and the ratio of maximum spurious signal amplitude effective value, can represent with dBc or dBFS.It represents that large-signal intermediate frequency ADC synchronously detects the ability of small-signal, numerically general larger than SNR (such as, the typical SNR of AD9042 is 65dB, and its SFDR is greater than 80dBC).SFDR may be the most important index of the ADC be applied in the communications field, the same important with three rank sections of low noise amplifier as frequency mixer.

TwoToneIMD double-tone intermodulation distortion (TwoToneIntermodulationDistortiom) refers to add two sinusoidal signals that frequency is close, amplitude is equal (6dB more than lower than full scale) to ADC, measure the effective value of third-order intermodulation product, the amplitude of a signal and the ratio of third-order intermodulation product amplitude are TwoToneIMD, and TwoToneIMD embodies multichannel ADC and resists the performance of disturbing mutually.Double-tone dynamic indicator also represents with TwoToneSFDR sometimes, and the difference of the two is that TwoToneIMD only considers third-order intermodulation product, and TwoToneSFDR considers all intermodulation products.

Improve the dynamic indicator of whole receiver, ADC dynamic property will be improved.For reaching high dynamic indicator, our way in specific works adds an arrowband dither signal at the input end of analog signal of ADC, its frequency band is outside the signal band of our care, general near DC and Nyquist frequency, because dither signal frequency band is very narrow, therefore little on SNR impact, but can SFDR be significantly improved.

Parsing module, UDP transceiver module, TCP transceiver module, user interface modular converter, data buffering control module, network parameter control module, network data distribution module, serial port protocol parsing module and Flash interface control module is integrated with in described network board.

Clock module design particular importance.On the one hand, the performance such as the making an uproar mutually of clock, spuious, shake is very big to ADC performance impact; On the other hand, clock signal frequency is high, intensity is large, is easy to become large interference source.We intend, and employing height is made an uproar mutually, the clock source of low jitter, and adopts the differential signal device drive clock of the low amplitude of oscillation, can reduce radiation intensity like this, and can improve anti-common mode radiation interference performance.
