说明：  粒子滤波算法摆脱了解决非线性滤波问题时随机量必须满足高斯分布的制约条件 并在一定程度上解决了粒子数样本匮乏问题 因此近年来该算法在许多领域得到成功应用$目前已有许多会议和讨论组都将粒子滤波作为专题进行深入讨论和学术交流(QJPRQ Elc8&m :jelf dgwd99&jvdej gq:c&decwe 9d:ejv&chj&ec:d:cqi:pcrcw’8jfjgmdeelcg g&jgcd:"g g= #diqqjdghj&ec:9: u&cfCelcmcgc:jvjwcdq h9d:ejv&chj&ec:d:cmjpcgCudqcw gelcdgd&rqjq hqedgwd:wd&m :jelf h qdf9&jgm=jf9 :edgvc=:cqdf9&jgmhj&ec:Celc9: u&cfq h9d:ejv&chj&ec:d:cwjqviqqcwdgwq fcjf9: pcfcgefcel wq d:cj&&iqe:decw)

等间距线性阵列，阵元数M=8，阵元间距d= λ /2，等幅加权，目标方位φr =0°。产生空间白噪声矢量（复高斯分布）。 设阵列信号矢量元素s(m)=exp[j mψr]，其信号幅度为1，该阵元接收机附加的高斯噪声为n(m)=nmr+jnmi，其中实虚部均为独立同分布N(0, σ2)的高斯随机数，则该通道合成信号x(m)=s(m) + n(m)，其中信噪比为： SNR = 10 lg[1/(2σ2)] = – 3 – 10 lg(σ2) (dB) (The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted target azimuth φR = 0. Space generated white noise vector (complex Gaussian distribution). Let array signal vector elements s (m) = exp [j mψr], the signal amplitude, the element receiver additional Gaussian noise n (m) = nmr+jnmi which the real and imaginary parts are independent and identically distributed N ( Gaussian random numbers of 0, σ2), the channel the synthesis signal x (m) = s (m) the PPLS n (m), where SNR is: SNR = 10 lg [1/(2σ2)] =- 3- 10 lg (σ2) (dB))

程序仿真了瑞利信道，分析和大量实测表明，多径效应使接收信号包络变化接近瑞利分布。在典型移动通信中，衰落深度达30dB左右，衰落速率约30~40次/秒。(Rayleigh channel simulation procedures, analysis and extensive test shows that the received signal multipath effect changes in the envelope close to the Rayleigh distribution. In a typical mobile communication, fading depth of about 30dB, the decline rate of about 30 to 40 times/sec.)
