Detailed description of the invention
The indoor barrier for radar experiment porch provided the present invention with specific embodiment below in conjunction with the accompanying drawings is anti-
Penetrate elimination system to be described in detail.
As shown in Fig. 1 Fig. 4, the indoor barrier reflection removal system bag for radar experiment porch that the present invention provides
Include microwave absorption room 1 and absorbing material 2;Wherein microwave absorption room 1 is the cuboid body structure that lower end is opening-like, covers on
The outside of the target positioning table 6 in radar experiment porch, face, front-end and back-end is respectively equipped with two doors that can outwards open
3;Either side bottom is provided with number hole 4 according to observations, for experimenter from microwave absorption room 1 external observation target to be measured 5
Position on target positioning table 6;Absorbing material 2 is attached on the inner surface of microwave absorption room 1, for absorption experiment indoor barrier
Hinder the noise signal that produce are raw.
Described absorbing material 2 is solid foam pyramid type absorbing material.
Described data observation port 4 is horizontal stripe shape, is opened in 8cm center, distance microwave absorption chamber 1 bottom surface, width × length
Degree is 8cm × 102cm.
The described indoor barrier reflection removal system for radar experiment porch also includes two vertical fixed strip 8 Hes
Article two, on activity bar 10, and microwave absorption room 1, the middle part of either side is additionally provided with a signal amplitude loophole 7, this side appearance
The position being positioned at signal amplitude loophole 7 both sides on face is respectively equipped with a vertical fixed strip 8, the top and the bottom of two vertical fixed strips 8
It is respectively formed with a square aperture 9;Article two, activity bar 10 be respectively inserted on two vertical fixed strips 8 two are corresponding opens
In mouth 9, for the first radar antenna 11 is clamped in signal amplitude loophole 7 middle part, it is additionally provided with on this side inner surface simultaneously
One sliding door that can be turned on and off signal amplitude loophole 7.
Described signal amplitude loophole 7 is square, a size of 10cm × 10cm.
Height × the width of described microwave absorption room 1 × a length of 104cm × 122cm × 132cm.
The using method of the indoor barrier reflection removal system being used for radar the experiment porch now present invention provided is explained
State as follows: when needing to utilize radar experiment porch to carry out the experimental teaching monitoring class course in the lab, first by this be
Microwave absorption room 1 in system covers on the outside of the target positioning table 6 in radar experiment porch, before or after microwave absorption room 1
The second radar antenna 12 being positioned at side, microwave absorption room 1 is opened and be directed to one of them on end face 3, by target 5 to be measured
It is fixed on the slide rail of target positioning table 6;If having only to utilize the second radar antenna 12 to launch electromagnetism to involve reception mesh to be measured
The echo of mark 5 reflection, utilizes the sliding door on the side inner surface of microwave absorption room 1 to be closed by signal amplitude loophole 7.Then is utilized
Two radar antennas 12 launch electromagnetic wave to target 5 to be measured, and the electromagnetic wave of other object scatter will in laboratory for target 5 to be measured
Being absorbed by absorbing material 2, therefore the second radar antenna 12 can only receive the electromagnetism reflected by target 5 to be measured by door 3
Ripple, thus can be according to the accurate location determining target 5 to be measured reflex time.If needing utilization to be arranged on signal amplitude loophole
The first radar antenna 11 on 7 launches electromagnetic wave, utilizes the second radar antenna 12 being positioned at side, microwave absorption room 1 to receive simultaneously
The echo of target 5 to be measured reflection, utilizes above-mentioned sliding door to be opened by signal amplitude loophole 7, then utilizes and is arranged on signal amplitude loophole 7
On the first radar antenna 11 launch electromagnetic wave, target 5 to be measured electromagnetism of other object scatter in laboratory to target 5 to be measured
Ripple will be absorbed by absorbing material 2, utilizes the second radar antenna 12 being positioned at side, microwave absorption room 1 to receive target 5 to be measured anti-
The echo penetrated, thus can be according to determining the accurate location of target 5 to be measured reflex time, it is achieved thereby that effective spy of target
Survey.
When Fig. 5 is experiment test, scope instruction (PPI) result of target echo to be measured.Wherein, Fig. 5 (a) is
The PPI not using present system shows result.Fig. 5 (b) shows result for using the PPI of present system.
The operating frequency setting radar experiment porch is 1 μ s as 9.35GHz, pulse width, pulse recurrence frequency 216Hz,
Maximum detectable range is 3.6m, and the rotating speed of the second radar antenna 12 is 9r/min, before target 5 to be measured is positioned at the second radar antenna 12
Side's distance between 180 °, and radar antenna 12 is 144cm.
From Fig. 5 (a), due to the restriction of experimental site, radar experiment porch is realizing the same of target 5 to be measured detection
Time, echo also contains substantial amounts of barrier clutter, thus have impact on the Radar Targets'Detection result in experimental teaching.
Keep experiment condition constant, target positioning table 6 arranges the room for radar experiment porch that the present invention provides
Test after interior barrier reflection removal system, shown in experimental result such as Fig. 5 (b).From Fig. 5 (b), compared to not using
The measurement result of present system, only occurs in that the radar of target 5 to be measured at the 144cm in 180 ° of the second radar antenna 12 front
Echo, clutter produced by other indoor barriers is the most suppressed, illustrate that present system can suppress indoor barrier effectively
Noise jamming, beneficially the carrying out of student experimenting project.
