The specific embodiment
See Fig. 1-5, the utility model concrete structure is as follows: antenna 1 is divided into upper, middle and lower row feedback 1A, 1B, 1C, each row feedback height 1.6m, each row feedback arranges reflecting plate 5,16 radiating elements 2 that on it, fixing assembling is arranged above and below, form antenna element battle array, radiating element 2 adopts existing microstrip structure dipole antenna; The signal input part of each radiating element 2 connects radio frequency electric switch (radio frequency electric switch adopts prior art) by radio-frequency cable 6; Radio frequency electric switches set is contained in box body 3.Upper, middle and lower row feedback is all arranged in shell, and by connector, three is linked into an integrated entity, aerial array overall length 4.8m, and antenna 1 is fixed on pedestal 4.Between upper, middle and lower row feedback 1A, 1B, 1C, by control cables 7, radio-frequency cable 8, connect (connected mode is prior art).
See Fig. 5, radio frequency electric switch adopts 48 way switch matrixes to be connected with 48 radiating elements, and the radiation of controlling each radiating element opens and closes, and the common port of radio frequency electric switch is by radio-frequency cable outer signal processor.During systems radiate signal, under the control of electronic switch, 48 radiating elements respectively separately radiation signal form the radiation beam that is numbered 1～48.
See Fig. 6,7, the course of work is as follows:
When the utility model is used, by a control cables and radio-frequency cable outer signal processor (prior art).
Little linear array is apart from radar certain distance (120 meters), and radar is demarcated to little linear array.Radar adds after radiation, and little linear array receives the signal of radar emission, through external signal processor.Form radar needed " echo-signal ".Again according to the elevation angle need to control electronic switch, " echo-signal " radiate from one of 48 radiating elements, by radar, received.Radar is confirmed this " echo-signal ".Now, radar obtains on trajectory the data of first.
In order to meet the requirement of radar extrapolation trajectory, radar need to obtain the data that on trajectory, N is ordered.Therefore, repeat above process, radar continues to transmit by its operation principle, and little linear array receives after radar emission signal, then radiate by radiating element.Process like this is certain number of times repeatedly, and radar obtains N data on trajectory, and these packets have contained the Ballistic Target five dimension data information (time, distance, speed, the elevation angle, amplitude) that little linear array forms, and can extrapolate and obtain cannon position coordinates.
exemplary applications
Artillery troops of this utility model Wo Junmou army are through on probation, show that system can be in outfield under the condition without artillery shooting, simulation generates the bullet target echo signal that firing position reconnaissance and calibration radar is surveyed, can realize the detection to firing position reconnaissance and calibration radar performance, can make again that Gun Position Radar is scouted under non-live shell state, operation is penetrated in school, strengthening radar operation hand fight operational capacity.
