Below in conjunction with accompanying drawing, the main of the embodiment of the present application technical scheme is realized principle, embodiment and be explained in detail the beneficial effect that should be able to reach.

S102: based on the width of described scanning beam, the beam saltus of any two adjacent wave interdigits when determining to launch described scanning beam;

Wherein, described beam saltus is specially the 1/M of the width of described scanning beam doubly, M be greater than 1 integer; Described based on described beam saltus and described guarded region, determine N number of ripple position of launching described scanning beam, be specially: described guarded region is divided into N number of region by described beam saltus, determine the N number of ripple position for launch described scanning beam corresponding with described N number of region.
Concrete, in the present embodiment, in order to improve the accurate detection of secondary radar to target, in scanning beam inquiry, select the answer signal be interfered in minimum preferred beam zone to determine the direction parameter of destination object as far as possible.Therefore, in the present embodiment, as shown in schematic diagram 2, the main beam width of the ripple position of phased-array antenna is divided into overlapping beam zone, zero dark beam zone and preferred beam zone.The feature of regional is as follows:
Overlapping beam zone: it is symmetrical about beam center axle, according to antenna radiation pattern by and difference thresholding set, in this region meet: with amplitude < spread degree+and difference thresholding;
Zero dark beam zone: i.e. difference beam region jumpy near beam center axle, width gets beam angle θ 3dB1/k, wherein the usual value of k is 10 ~ 15, and due in zero dark beam zone, when destination object is far away, answer signal is limited to the internal noise of receiving device, thus causes the direction parameter of destination object cannot Obtaining Accurate;
Preferred beam zone: it is preferred in reality detecting order target area, namely removes the region beyond zero dark beam zone and overlapping beam zone in main beam.
When formulating beam scanning strategy, first width and the guarded region of the scanning beam of phased-array antenna is obtained, according to the region of secondary radar system monitoring, it is divided into several ripple positions of continuous print by azimuth plane, when the ripple figure place of design partition, sweep all standing of wave beam to target detection spatial domain mutually for what ensure phased array secondary radar, the beam saltus of adjacent wave position should be less than the beam angle of phased array antenna, that is: θ/N< θ 3dB, wherein, θ 3dBfor the beam angle of phased array antenna azimuth plane, θ represents secondary radar identification zone scope, and N is the ripple figure place of design partition.When each beam scanning inquiry, in order to ensure measuring accuracy, destination object need be made to be arranged in the preferred beam zone of the corresponding scanning beam at least one ripple position, N number of ripple position of division, so beam saltus is specially the 1/M of the width of scanning beam doubly, M can set according to actual conditions, such as, being set as 3,4,5,6 etc., can also be other numerical value, at this, the application does not limit.
As shown in Figure 3, a kind of ripple position partition strategy for the present embodiment provides: when the overlapping wave beam district, left side of prewave position wave beam is positioned at the preferred beam zone of last wave beam, the preferred beam zone of a wave beam after the crossover region, right side of prewave position wave beam is positioned at, should be positioned at emphasis for initial ripple position with the overlapping beam zone terminating ripple position and monitor outside the scope of spatial domain; When zero dark beam zone of prewave position wave beam had both been positioned at the preferred beam zone, right side of last wave beam, the preferred beam zone, left side of a wave beam after being positioned at again, the preferred beam zone, left side of a wave beam after being positioned at for its zero dark beam zone, initial ripple position, is positioned at the preferred beam zone, right side of last wave beam for end ripple position.Such as: guarded region is 120 degree, the width of the scanning beam of phased-array antenna is 6 degree, and the beam saltus of adjacent wave position is taken as 1/3 of beam angle, namely 2 degree, now, and by guarded region be 120 degree by 2 degree for interval is divided into 60 regions, thus, the ripple figure place of division is 60.
After having divided ripple position, scan successively by ready-portioned ripple position with regard to gated sweep wave beam, like this, keep off and working as prewave bit scan to destination object, and when determining the favored area that destination object is positioned at when the scanning beam of prewave position correspondence, just the answer signal of solving target object transmission, obtains the direction parameter corresponding with destination object.Determining that destination object is not when being positioned at the favored area when the scanning beam of prewave position correspondence, show that the answer signal that destination object sends is disturbed seriously, destination object orientation accurately cannot be calculated according to answer signal, so, directly abandon the answer signal received, and carry out the scanning of next ripple position, and then when next ripple position transmit scan beam, destination object can be made to be positioned at preferred beam zone corresponding to the scanning beam of next ripple position, and then, in upper once scanning, obtain the accurately direction parameter corresponding with destination object.By such mode, like this, make monitoring objective can be positioned at preferred beam zone, avoid wave beam crossover region and zero dark beam zone, avoid the impact of interference region on answer signal, and then the answer signal obtained can react the orientation of destination object exactly.So, effectively can solve the technical matters that the direction parameter error of existence monitoring acquisition destination object in prior art is larger, avoid the false-alarm possible when destination object detects or undetected situation, improve the accuracy of secondary radar angle measurement and the accuracy rate of target detection.
Further, in the present embodiment, judge whether destination object is positioned at the preferred beam zone of the scanning beam when prewave position correspondence, realizes mainly through following steps:
Corresponding with described answer signal with range value and the difference of the spread angle value corresponding with described answer signal be greater than preset and difference thresholding time, judge whether described destination object is positioned at zero dark beam zone of described scanning beam, obtains the first judged result;
Wherein, when described first judged result is no, characterizes described destination object and be positioned at preferred beam zone corresponding to described scanning beam.
Judge described the zero dark beam zone whether described destination object is positioned at described scanning beam, before obtaining the first judged result, described method also comprises:
By the described and range value with passage acquisition of receiver; And obtain described spread angle value by the poor passage of described receiver;
Judge whether described and range value and described spread angle value difference is greater than described presetting and difference thresholding, obtains the second judged result;
When described second judged result is for being, perform step: judge whether described destination object is positioned at zero dark beam zone of described scanning beam, obtains the first judged result.
Wherein, describedly judge the zero dark beam zone whether described destination object is positioned at described scanning beam, to obtain the first judged result, specifically comprise:
Resolve described answer signal, obtain the first orientation parameter that described destination object is corresponding;
Based on described first orientation parameter, judge whether the distance between the position at described destination object place and the central shaft of described scanning beam is less than predetermined threshold value, obtain the 3rd judged result;
Based on described 3rd judged result, judge whether described destination object is positioned at zero dark beam zone of described scanning beam, obtains described first judged result;
Wherein, when described 3rd judged result is for being, described first judged result is yes, shows that described destination object is positioned at zero dark beam zone of described scanning beam.
Concrete, in the present embodiment, when after sending scanning beam when prewave position, and when obtaining the answer signal of destination object transmission, can by avoiding on the main beam border easily affected by noise and antenna out-of-roundness etc. overlapping beam zone with difference threshold technique, further, also based on answer signal, zero can be carried out and deeply filters.Concrete, after electronic equipment receives the answer signal of destination object transmission, this answer signal respectively by with passage with difference passage, and then can obtain corresponding to range value and spread angle value, determine whether destination object is positioned at the overlapping beam zone on main beam border according to default and difference thresholding in electronic equipment, such as: when presetting and difference thresholding is 6dB, its width is assumed to 0.6 degree, what detect acquisition is-60dB with range value, when spread angle value is-68dB, owing to being 8dB with the difference of range value and spread angle value, be greater than and preset and difference thresholding 6dB, now, determine that destination object is not the overlapping beam zone being positioned at main beam border.
Further, after determining that destination object is not the overlapping beam zone being positioned at main beam border, also need to judge whether destination object is positioned at zero dark beam zone corresponding to scanning beam.Concrete, by the answer signal that solving target object sends, obtain first orientation parameter corresponding with it, such as: acquisition be 18dB with the difference of amplitude and spread angle value, and then 0.2 degree of orientation place of the main lobe wave beam being positioned at Current Scan wave beam can be obtained by the antenna bearingt table prestored, suppose that zero dark region is for [-0.3 degree, 0.3 degree], can determine that destination object is positioned at zero dark beam zone of Current Scan wave beam thus.And then destination object is not positioned at the preferred beam zone when prewave bit scan wave beam.And for example: acquisition be 15dB with the difference of amplitude and spread angle value, and then 1 degree of orientation place of the main lobe wave beam being positioned at Current Scan wave beam can be obtained by the antenna OBA table prestored, suppose that zero dark region is for [-0.3 degree, 0.3 degree], can determine that destination object is not positioned at zero dark beam zone of Current Scan wave beam thus.And then destination object is positioned at the preferred beam zone when prewave bit scan wave beam.After determining that destination object is positioned at preferred beam zone, the direction parameter calculated according to answer signal is preserved.After determining that destination object is not positioned at preferred beam zone, now, be inaccurate according to the direction parameter that answer signal calculates, and then without the need to keeping this direction parameter, so, carry out the beam scanning of next ripple position, and then, scan destination object at the scanning beam of next ripple position, and this object is positioned at corresponding preferably beam zone, next ripple position, thus obtains the direction parameter accurately that calculates and preserve this direction parameter.
Due to less at the beam saltus of setting, the answer signal that destination object sends all may can be detected in continuous several ripple position, and then the direction parameter calculated may comprise multiple, in order to obtain direction parameter more accurately, method in the present embodiment, step: based on described answer signal, obtains the direction parameter corresponding with described destination object, specifically comprises:
When described phased-array antenna sends scanning beam in described i ripple position, obtain the answer signal that described destination object sends, P be greater than 0 integer;
Based on described answer signal, obtain P the second orientation parameter corresponding with described destination object;
Based on described P second orientation parameter, determine the direction parameter corresponding with described destination object.
Wherein, described based on described P second orientation parameter, determine the direction parameter corresponding with described destination object, specifically comprise:
Calculate the mean value obtaining described P second orientation parameter;
Using described mean value as the direction parameter corresponding with described destination object.
Concrete, in the present embodiment, concrete phased-array antenna at the scanning beam that a ripple position is launched time, the answer signal received comprises multiple pulse, therefore the direction parameters such as multiple position angle corresponding with destination object, the elevation angle can be calculated based on answer signal, now, a direction parameter can be determined based on the strategy preset.Such as: go out to launch P scanning beam the ripple position of 0 degree, obtain P the pulse corresponding with answer signal, obtain P position angle of destination object after resolving P pulse, ask for P azimuthal mean value, and then determine that this mean value is the position angle of destination object.
Further, due to when adjacent multiple ripple position place all can scan destination object, described method for supervising also comprises the steps:
When described phased-array antenna all can scan described destination object at Q ripple position place, getting j is successively 1 to Q, obtain the answer signal of the described destination object transmission when jth ripple position, based on the described answer signal that described destination object sends when jth ripple position, obtain P the second orientation parameter corresponding with described destination object when jth ripple position; Calculate the mean value obtaining described P second orientation parameter; Based on described mean value, calculate the mean square deviation obtaining a described P direction parameter; Amount to and obtain Q mean square deviation, Q is the integer being greater than 1 and being less than or equal to N;
Obtain P the second orientation parameter that mean square deviation minimum in a described Q mean square deviation is corresponding, based on described P second orientation parameter, determine the direction parameter corresponding with described destination object.
Concrete, in the present embodiment, due to destination object may can be scanned at multiple ripple position place, so, when existence can scan destination object at Q ripple position place, the size of the mean square deviation that P the direction parameter that can obtain according to ripple position each in Q ripple position is corresponding determines the direction parameter that destination object is final.Such as: when 0 degree of ripple position, can scan destination object, phased-array antenna sends scanning beam, and then receives the answer signal of destination object transmission, calculate 5 direction parameters by answer signal, calculate and obtain the first mean square deviation corresponding to these 5 direction parameters.Meanwhile, when 2 degree of ripple positions, also destination object can be scanned, phased-array antenna sends scanning beam, and then receive the answer signal of destination object transmission, calculate 4 direction parameters by answer signal, calculate and obtain the second mean square deviation corresponding to these 4 direction parameters.And then, owing to scanning destination object at two ripple potential energies, and then obtain the first mean square deviation and the second mean square deviation totally two mean square deviations, and, first mean square deviation is less than the second mean square deviation, so, determine that the direction parameter that 0 degree of ripple position detects is more accurate, and then determine the direction parameter of mean value destination object the most of 5 direction parameters of 0 degree of ripple position correspondence.The main mode with mean square deviation is described in detail in the present embodiment, but in specific implementation process, the mode such as mean value or root-mean-square error can also be adopted to determine the direction parameter that destination object is final, and at this, the application is not restricted.By such mode, electronic equipment is when utilizing scanning beam to scan successively by ready-portioned ripple position, when the direction parameter that the same destination object obtained is corresponding comprises multiple, the most accurate direction parameter can be determined by preset strategy, so, achieve the technique effect of accurate localizing objects object.
