Description
Technical field
The invention belongs to measuring system and measuring method on a kind of lake of sonar system directive property.
Background technology
The directive property of sonar system is to guarantee that equipment finishes the important indicator of predetermined function.The directivity measurement of General System needs to carry out in the pond.Sound source transmits, and rotates the output level that basic matrix utilizes the level recorder register system simultaneously.Utilize level recorder to measure wave beam, once can only measure a wave beam, efficiency of measurement is low.For multiple-beam system, adopt above-mentioned method to measure the directive property of each wave beam passage one by one, workload will be very big.At present domestic on the lake, be that the manual read fetches wave amplitude, the pointwise record to the measuring method of basic matrix directive property; Measuring method to sonar system directive property is also just utilized level recorder, draws main beam.The directive property that adopts these two kinds of methods to measure sonar system on the lake all can't measure the directive property of system complete, even can't measure under the bad situation of condition at all.Flowing of lake water makes sound source and position between the reception basic matrix that relative motion constantly take place, and the data error that records like this is bigger, and especially narrower and must be under situation about measuring on the larger distance at wave beam, measuring error be then bigger, even can't measure at all.
How to measure abroad at present, yet there are no the report of any form documents and materials for sonar system directive property in the waters.
Summary of the invention
The objective of the invention is on the lake, to carry out the shortcoming of field survey in order to overcome traditional sonar system directivity measurement method, measuring system and measuring method thereof on a kind of sonar system directive property lake is provided, promptly utilize data acquisition system (DAS), add that range gate control realizes the method that wave beam is measured.This method has not only solved because of the flowing of lake water, sound source with receive position between the basic matrix and relative motion constantly takes place cause wave beam to measure the problem of difficulty, the while has also been improved efficiency of measurement greatly.This method is easy to use flexibly, efficiency of measurement is high, and one-shot measurement can obtain the data of all wave beams, and measurement data can be stored in the computing machine, can print at any time.
Formation of the present invention mainly is that sound source [1], sonar system [2], data acquisition circuit [3], computing machine [4], circuit for generating synchronous signals [5] and basic matrix wheelwork [6] are formed.Wherein sound source [1] is made up of signal source [7], power amplifier [8] and transducer surveying instruments such as [9], sonar system [2] comprises that receiving basic matrix [10], reception and wave beam formation circuit [11] is system under test (SUT), and data acquisition circuit [3] and computing machine [4] can be measuring equipments, also can be the parts of tested sonar system.Measuring method is: the preliminary work before the first step is measured, start the suitable short-period CW pulse of sound source [1] Xiang Shuizhong emission amplitude, rotating basic matrix wheelwork [6] makes reception basic matrix [10] corner place initial position, the echoed signal that receives in basic matrix [10] the reception water forms circuit [11] beamformer output signal through reception and wave beam, be added to the input end of data acquisition circuit [3] then, with the input signal of oscillograph observation data Acquisition Circuit [3], the tester adjusts circuit for generating synchronous signals [5] makes synchronizing signal synchronous with the pulse echo signal that receives; Second step was carried out the beam data collection, in the constantly suitable short-period CW pulse of emission amplitude in water of sound source [1], when receiving basic matrix [10] by basic matrix wheelwork [6] quick rotation, data acquisition circuit [3] is stored in the beam data that collects in the computing machine [4] according to the synchronizing pulse that circuit for generating synchronous signals [5] produces; The 3rd step was drawn the directivity pattern of sonar system [2], on computing machine [4] or other computing machine, utilized application software the beam data that collects to be depicted as the directivity pattern of sonar system [2].Measuring task is finished.The CW pulse signal of sound source [1] emission is short-period pulse signal, and sound source [1] is determined by measurement requirement with the distance that receives basic matrix [10]; Basic matrix wheelwork [6] and reception basic matrix [10] mechanical connection can rotate reception basic matrix [10] towards any direction; Data acquisition circuit [3], computing machine [4] can be the parts of measuring system, also can be the parts of tested sonar system [2]; Circuit for generating synchronous signals [5] is to utilize tested sonar system [2] to carry computing machine [4] when measuring in order to solve, owing to data storage cell memory capacity is set inadequately, data acquisition circuit [3] can be according to synchronizing signal, only gather one section beam data that echoed signal is arranged, when data storage cell memory capacity is enough big, can not add circuit for generating synchronous signals [5], the data acquisition circuit of measuring system [3] can directly be gathered beam data, and the beam data that collects is stored in the computing machine [4].
If this measuring system changes sound source [1] into phase place controlled signal source, remove the directive property that this method of reception basic matrix [10] can also be used for laboratory measurement sonar system [2] reception and wave beam formation circuit [11].
In sum, the present invention has been owing to adopted data acquisition technology, make this measuring method possessed easy flexibly, efficiency of measurement is high, one-shot measurement can obtain the data of all wave beams, and measurement data can be stored in the computing machine advantage that can print at any time; Because this method measuring speed is fast, can also reduce greatly since lake water flow the error of the measurement data that causes.In addition, this measuring method make full use of system under test (SUT) self with data acquisition circuit and computing machine, reduced and measured used instrument and equipment.The present invention is applicable to fully on various corresponding waters or in the pond sonar wave beam formation circuit and system's directive property is measured.
