In the utility model preferred embodiment, described chirping of birds object detection method (as Fig. 4) comprises the following steps:

At first M non-directional microphone formed microphone array according to certain topological structure, as Fig. 3 example, 9 microphones are evenly distributed on the plane that the 3 d space coordinate axle opened, in the actual environment of airport, target location and microphone distance are larger, can think that the signal amplitude (acoustic pressure) that each array element of microphone array collects is changed to zero, this moment, Acoustic Wave Propagation can be thought plane wave propagation.

For ease of statement, 2 non-directional microphone array elements that we choose are wherein carried out the computational methods description.As Fig. 3 example, microphone 1 and microphone 2 receive the distance and bearing of the acoustical signal of same chirping of birds sound source P, have reflected the distance and bearing angle of bird target and microphone line.

Step 1: by target to the two anemochoric path differences of Mike, build geometrical relationship:

In space coordinates, we suppose that acoustical signal that P sends is L to microphone 1 and microphone 2 apart from difference ₁₂, L so ₁₂=L _1p-L _2p, establish microphone 1 and be origin of coordinates r ₁=(x ₁, y ₁, z ₁)=(0,0,0), L so _1p=R _p

R wherein ₂=(x ₂, y ₂, z ₂), r _p=(x _p, y _p, z _p), got by geometrical relationship in Fig. 3:

${(R_p+L_{12})}^2=R_2^2-2r_2^T{r}_p+R_p^2$ ①

This moment our hypothesis L ₁₂Known, 1. equation is strictly set up equation expansion so:

$R_2^2-L_{12}^2-2R_p{L}_{12}-2r_2^T{r}_p=0$ ②

L in the actual operation process ₁₂The method of using time delay to estimate, the acoustical signal that estimating target P sends is to the transmission time τ of microphone 1 and microphone 2 ₁₂Obtain, namely (wherein c is the aerial spread speed of sound, is 340m/s under normal temperature), therefore 2. formula does not strictly equal 0, and establishing error amount is ε, and 2. formula is out of shape:

$\mathrm{\ϵ}=R_2^2-{\hat{L}}_{12}^2-2R_p{\hat{L}}_{12}-2r_2^T{r}_p$ ③

Step 2: build the internodal equation group of multi-microphone:

When microphone array is comprised of M microphone, can utilize a plurality of microphone path differences to build in twos equation, solving equations improves target location accuracy.Be exemplified as 9 microphones as Fig. 3, at initial point, for ease of calculating, we select microphone 2～microphone 9 and microphone 1 to build in twos equation group because of microphone 1.Be similar to step 1:

$\mathrm{\ϵ}=\left[\begin{array}{c}{R}_2^2-L_{12}^2\\ .\\ .\\ .\\ R_9^2-L_{19}^2\end{array}\right]-2R_p\left[\begin{array}{c}{\hat{L}}_{12}\\ .\\ .\\ .\\ {\hat{L}}_{19}\end{array}\right]-2\left[\begin{array}{ccc}{x}_2& y_2& z_3\\ .& .& .\\ .& .& .\\ .& .& .\\ x_9& y_9& z_9\end{array}\right]\left[\begin{array}{c}{x}_p\\ y_p\\ z_p\end{array}\right]$ ④

Wherein: $R_p=\sqrt{x_p^2+y_p^2+z_p^2}$

Step 3: the method for using the time delay estimation is obtained

By ${\hat{L}}_{12}={\mathrm{\τ}}_{12}\×c$ ⑤

Wherein

Be the path difference between two microphones, c is the aerial spread speed of sound, is 340m/s under normal temperature, τ ₁₂To the delay volume between microphone microphone 1 and microphone 2, it utilizes the time difference of two signal correction the maximum value of functions to obtain for same chirping of birds sound source P.

If obtain respectively f after the A/D sampling of the target acoustical signal that microphone 1 and microphone 2 receive process and LPF _1p(n) and f _2p(n).

f _1p(n)=s(n-τ ₁)+N ₁(n)

f _2p(n)=s(n-τ ₂)+N ₂(n)

Its cross-correlation function is:

P ₁₂(τ)=E(f _1p(n)f _2p(n-τ)) ⑥

Suppose that acoustical signal s (n) is uncorrelated with noise signal N (n): the following formula abbreviation gets:

P ₁₂(τ)=P _s(τ-(τ ₁-τ ₂)) ⑦

By the character of correlation function P as can be known ₁₂(τ) there is peak value P _12max(τ), and when value be P _12max(τ), the correlation of two signals is best, and we think direct signal to receive signal, at this moment signal time delay τ ₁₂Equal τ in formula ₁-τ ₂That is: τ ₁₂=τ ₁-τ ₂

To f _1p(n) and f _2p(n) carry out FFT:

F _1p(k)=FFT(f _1p(n))，F _2p(k)=FFT(f _2p(n)) ⑧

7. can receive the crosspower spectrum of signal by formula:

$G_{12}\left(k\right)=F_{1p}\left(k\right)F_{2p}^{*}\left(k\right)$ ⑨

:

P ₁₂(τ)=FFT ^-1(G ₁₂(k)) ⑩

To P ₁₂(τ) search for, with spectrum peak bring into formula 7. with formula 5., can obtain

Recycle step 3, utilize microphone 1 and microphone 2～microphone 9 to make up in twos, can try to achieve

Step 4: calculated target positions coordinate

In being brought into step 3 acquired results 4., under minimum mean square error criterion::

$(x_p,y_p,z_p)={({\left[\begin{array}{ccc}{x}_2& y_2& z_3\\ .& .& .\\ .& .& .\\ .& .& .\\ x_9& y_9& z_9\end{array}\right]}^T\·\frac{1}{\mathrm{\Δ}}\begin{array}{c}\left[\begin{array}{cccc}1-L_{12}^2& -L_{12}{L}_{13}& ...& -L_{12}{L}_{19}\\ -L_{13}{L}_{12}& 1-L_{13}^2& ...& -L_{13}{L}_{19}\\ .& .& .& .\\ .& .& .& .\\ .& .& .& .\\ -L_{19}{L}_{12}& -L_{19}{L}_{13}& ...& 1-L_{19}^2\end{array}\right]\·\left[\begin{array}{ccc}{x}_2& y_2& z_3\\ .& .& .\\ .& .& .\\ .& .& .\\ x_9& y_9& z_9\end{array}\right]\end{array})}^{-1}\·{\left[\begin{array}{ccc}{x}_2& y_2& z_3\\ .& .& .\\ .& .& .\\ .& .& .\\ x_9& y_9& z_9\end{array}\right]}^T\·\frac{1}{\mathrm{\Δ}}\left[\begin{array}{cccc}1-L_{12}^2& -L_{12}{L}_{13}& ...& -L_{12}{L}_{19}\\ -L_{13}{L}_{12}& 1-L_{13}^2& ...& -L_{13}{L}_{19}\\ .& .& .& .\\ .& .& .& .\\ .& .& .& .\\ -L_{19}{L}_{12}& -L_{19}{L}_{13}& ...& 1-L_{19}^2\end{array}\right]\·\frac{1}{2}\left[\begin{array}{c}{R}_2^2-L_{12}^2\\ .\\ .\\ .\\ R_9^2-L_{19}^2\end{array}\right]$

(wherein $\mathrm{\Δ}=L_{12}^2+L_{13}^2+...+L_{19}^2$ ）
