提出了一种新的实时雷达脉冲信号检测算法,该算法首先将数据分为两路,对一路进行单点滑动、取共轭,然后与另一路信号相乘,再累加、取模,最后与门限比较,得到检测结果。算法具有递推和流水结构,硬件实现时只需一个复数乘法器、一个复数加法器、一个复数减法器和一个复数取模运算器。在此采用一阶扰动分析,推导了算法起始点检测误差的解析式,给出了算法性能边界,仿真结果验证了理论推导的正确性。与其他信号检测算法相比,该算法结构规整,易于硬件应用,可实现实时检测。
A new real-time radar pulse signal detection algorithm is proposed, which first divides the data into two paths, performs a single-point sliding on one path, conjugates it, multiplies it with the other path signals, accumulates and modulo the signal, Threshold comparison, the test results. The algorithm has recursion and pipeline structure. When the hardware is implemented, only one complex multiplier, one complex adder, one complex subtractor and one complex modulus operator are needed. First-order perturbation analysis is used to derive the analytic formula of the initial detection error of the algorithm, and the performance boundary of the algorithm is given. The simulation results verify the correctness of the theoretical derivation. Compared with other signal detection algorithms, this algorithm has the advantages of structured structure, easy hardware application and real-time detection.
