Layer, and with random combine and can put in order and can exchange at random between each dielectric layer.Hereby based on multiplayered discontinuity medium wall
Layer comes simulating actual conditions and fixed material, and cooperates transformation combined method to constitute the probe field for building radar life-detection instrument
Scape is achieved in comprehensive test to radar life-detection instrument detection performance.
Referring to Fig. 1 which shows the detection system of the radar life-detection instrument constituted based on the above principles in this example
Structural schematic diagram.
As seen from the figure, this radar life-detection instrument performance detecting system 100 is mainly by detection scene simulator 110, rail
Road mobile device 120, manikin simulating equipment 130 and control device (not shown), which cooperate, to be constituted.
Detection scene simulator 110 in this system is used for analog detection scene.Its mainly by swivel base 111, with
And the 112 phase interworking of multiplayered discontinuity dielectric layer being arranged on swivel base is constituted, and each layer in multiplayered discontinuity dielectric layer
Between sequence can exchange at random.
Since radar detection subtended angle is generally each 60 ° in left and right, amount to 120 ° of range, this example is using the rotation bottom rotated
Disk 111 carrys out pedestal, to carry multiplayered discontinuity dielectric layer 112.
A placement track 113 is provided on the swivel base 111, to dispose multiplayered discontinuity dielectric layer 112 for activity,
And make between multiplayered discontinuity dielectric layer 112 can random combine and can exchanging at random put in order, improve simulation effect.
For the specific constructive form of the swivel base 111 can according to demand depending on, rotation for chassis can be by artificial
Mode drives or is driven automatically by driving part.
As shown in Fig. 2, the dielectric layer of this example optimum selecting three-layer unlike material is constituted for multiplayered discontinuity dielectric layer 112,
Including first medium layer 112a, second dielectric layer 112b, third dielectric layer 112c.This three Layer Detections dielectric layer all uses identical ruler
Very little cube structure, preferred profile size (length, width and height) are 2m × 2m × 0.3m cube structure.
Meanwhile first medium layer 112a medium 1 is built by wall-building brick and mortar, second dielectric layer 112b is by prefabricated board

Manikin simulating equipment 130 in this system is placed on the hoistable platform 125 in track mobile device 120, is used for
Simulate the human body with vital sign signals.
It is preferably able to the beacon instrument of simulation human life characteristic signal in this example to constitute, human body respiration can be simulated
Frequency and corresponding simulated respiration amplitude.The beacon instrument is placed on hoistable platform 125, and the drive on hoistable platform 125
The height adjustment of 1.55M~1.85M is able to carry out under dynamic, in mode the height of different human body, to improve the accuracy of test.
In specific implementation, it is contemplated that the needs of multiple target detection can be arranged two sets and two in track mobile device 120
A above manikin simulating equipment, so that multiple manikin simulating equipments (beacon instrument) are not on the same axis, for detecting radar
Detect two and more than two Multiple Target Signals.
In the more set manikin simulating equipments of setting, more sets are set on the first straight line track 121 of track mobile device 120
By first movement disk platform 122, second straight line track 123, the second mobile platform 124 and hoistable platform 125 match composition
Mobile platform mechanism, and corresponding manikin simulating equipment (beacon instrument) is disposed on it.
It is accurate in search coverage for manikin simulating equipment 130 is driven in this system by track mobile device 120
Mobile scheme, this example give an alternative, which is using wheel type mobile mobile mechanism and camera
The scheme matched carrys out alternate track mobile device 120.
In the alternative solution, bogey of the wheel type mobile mobile mechanism as manikin simulating equipment 130, by control device
Control, can drive manikin simulating equipment 130 to move freely in search coverage, and the top of search coverage is arranged in camera,
For demarcating the position for dividing wheel type mobile mobile mechanism in search coverage, is fed back as error, form closed-loop control, thus
Accurately to control wheel type mobile mobile mechanism and drives motion direction of the manikin simulating equipment 130 in search coverage.
Control device in this example drives manikin simulating equipment 130 in probe field for controlling track mobile device 120
It is moved in the search coverage of scape simulator, while the vital signs letter of the generation of manikin simulating equipment 130 can also be controlled to adjust
Number.
Control device in this example can be realized by wireless or effective mode to 120 He of track mobile device
The control of manikin simulating equipment 130.
Furthermore diversified forms can be used to realize in the control device, and such as setting is controlling indoor PC machine, is being placed in test
Mobile terminal of control system etc., specifically depending on actual needs.
The radar life-detection instrument performance detecting system 100 constituted based on above scheme can be realized long-range wireless remote control,
The open and close of adjustment front and rear, left and right, just distance and beacon instrument, the accurate rotation angle of turntable can be used for radar detection energy
The full-automatic Blind Test of power is examined.
