The signal received after dynamic；The flow chart of microcontroller is as shown in figure 9, microcontroller can work under various modes and can generate not
With the control signal of pattern, the operating mode of radar system control single chip computer；It can provide one to microcontroller during system boot
The enabling signal of beginning, this signal have 2 kinds of patterns, and pattern one is：1 kind 0-360 ° are surveyed one group of data every 2 °, survey 180 altogether
Group data.Pattern second is that：Forward and reverse each 90 ° of survey, surveys one group of data every 2 °, surveys 90 groups of data altogether centered on normal direction；
It is that the counter of microcontroller starts counting up first when carrying out the operation of pattern one, and the stored count time, when accumulative
Between when reaching 10 seconds, counter sends out a pulse to driving circuit, and the direction of reception antenna body 1 is moved to the left 2 °, and receives
The signal sent with the record direction the first radar station signal transmitting system；Then start counting up again, in cycles, and add up to send
The number of the pulse gone out, when pulse number reaches 180, counter stops counting, and resets；
When carrying out the operation of pattern two, the counter of microcontroller starts counting up, and the stored count time, reaches when the accumulative time
At 10 seconds, counter sends out a pulse to driving circuit, and the direction of reception antenna body 1 is moved to the left 2 °, and receives and record
The signal that the direction the first radar station signal transmitting system is sent；Then start counting up again, in cycles, and the accumulative arteries and veins sent out
The number of punching, when pulse number reaches 45, counter stops counting, and resets to original state i.e. normal direction state；
Then the counter of microcontroller starts counting up again, and the stored count time, and when the accumulative time reaching 10 seconds, counter is sent out
To driving circuit, the direction of reception antenna body 1 moves right 2 °, and receives and record the first radar station of direction letter for one pulse
The signal that number emission system is sent；Then start counting up again, in cycles, and the number of the accumulative pulse sent out, when pulse
When number reaches 45, counter stops counting, and resets to original state i.e. normal direction state；Under this pattern, day is received
Wire body 1 has first turned left 90 °, has received 45 groups of data, is then back to origin, then turns right 90 ° and have received 45 groups of data,
Then origin is returned again to, takes 15 minutes.
If two radar stations are relatively far apart, when record is given in the weaker inconvenience of signal received, spectrum monitoring can be passed through
Unit and spectrum utilization state display device choose the signal source of noise source relatively stable near working frequency as test, generally
In the case of, range value is smaller for working frequency, and range value is larger for noise frequency, as long as noise frequency is stablized, we are just
Noise source can be used it as to test, test method is same as above, and test system tests reception antenna side automatically during start every time
Xiang Tu.
The data processing unit 6 receives signal for processing and generates actual measurement directional diagram；The data processing unit 6 obtains
The reception signal data of different azimuth in angular range is taken, is stored by certain form, generates corresponding directional diagram and automatic school
Just original directional diagram；While test is started shooting, data processing unit 6 receives the signal in each orientation, i.e. reception antenna
The every turn of 2 ° of data processing units 6 of body 1 will receive one group of data, and data include range signal, phase signal etc.；Pattern one surveys one
Secondary directional diagram needs 30 minutes, measures 180 groups of data, and pattern two is surveyed a directional diagram and needed 15 minutes, the 90 groups of data measured；Then
A fixed region need to be placed the data in by certain form, during Pattern measurement, is also surveyed data
Directional diagram correction process.
In embodiments of the present invention, in test, the content that obtains specifically has time of test data, antenna frequencies, antenna
Port number, monopole intersection loop antenna have 3 passages（Monopole, cosine ring, sinusoidal rings）Gain, phase, test angle model
It encloses（LOOK LEFT, LOOK RIGHT）；If every 1 degree of test once, amount to 180 antenna datas；The content of acquisition further includes each
Corresponding loop antenna amplitude under a test angle, such as on the basis of monopole, monopole, cosine ring, sine after normalization
The amplitude of ring.
In embodiments of the present invention, the first radar station and the second radar station are merely represented in measurement reception diagram phase
Two different radar stations, do not represent specifically which radar station for；Two radar stations are equipped with corresponding signal
Emission system and test system, the first radar station can receive day using the signal that the second radar station emits to survey the first radar station
The directional diagram of line, similary second radar station can also receive day using the signal that the first radar station emits to measure the second radar station
The directional diagram of line, but the two radar stations cannot be carried out at the same time measurement, because its letter when measuring of the website as measurement
Number emission system is to close, and this is done to ensure measurement accuracy, two radar stations are also impossible to together in actually measuring
When measure.
The advantages of embodiment of the present invention is：
1）Reception diagram error is small, and Effect on Detecting is accurate
Present invention employs two radar stations to be mutually measured, the fixed radiofrequency signal of the first radar station signal emission module transmitting, and second
The reception antenna body 1 of radar station presses certain direction and angular turn, while receives what each first radar station of angle was sent
Signal so as to obtain the reception data of certain angle scope, obtains the directional diagram of field measurement in this way；Due to being scene
The directional diagram of test, it handles data for radar and provides real foundation；Due to starting shooting every time（Including system reboot）Automatically
Test, it is also considered that the real-time change factor of environment；The present invention solves bathometer antenna system due to setting up site environment
