In this paper a group of sequencss wtih a δ-function autocorrelation are defined as the complementary-type sequences.Six kieds of sequences are presented and compared, and then it is shown that the basic form among them is the complementary series, and the others can be derived or generalized from it.The progresses of signal processing techniques have now led to a successful development of the complementary series phase reversal coded pulse compression radars, which have a low range sidelobe level within a narrow doppler spread range. A pair of the complementary series can be isolated from each other via time-sharing, frequency sharing, etc. The optimal pairs of complementary series and the optimal series should be selected according to the sidelobe level of the ambiguity function that is as low as possible.It had been demonstrated that the compleimntary series formed by concatenating, interleaving and mating, provide some radio navigation systems, such as Loran-C, with the possibilities of supressing the sky wave interference, automatic searching, recognizing and tracking.The complementary series also find its applications in the acoustic surface, -wave transducer coding and the infrared spectrometry.

本文定义自相关为δ函数的一大类序列为互补型序列,介绍了六种序列,指出互补型序列的基本形式是互补序列,而其他序列都可由互补序列导出或推广而来。 当前由于信号处理技术的进展,能在较窄多普勒范围内得到低距离旁瓣的互补序列倒相编码脉冲压缩雷达已经问世。这种雷达可以用时分、频分等方法隔离序列,最佳互补序列对和最佳序列应该选择模糊函数的旁瓣为最低的。 曾证明过,如Loran-c这样的无线电导航系统,采用按链接、插接、取伴偶步骤构成的互补序列,能够具有抑制天波干扰,自动搜索、识别和跟踪的能力。 互补序列在声表面波换能器编码和红外线光谱测定中也有应用。

Described here is a new style, cardiac pacing system—an implantable pacemaker with the programmability of parameters. It consists of a programmer and an implantable pacemaker with a digital memorial element. Whenever an adjustment is neccessary, the pacemaker can be manipulated to a new stable state with the programmer emitting a series of coded pulses toward it. The process of adjustment is quick and noninvasive.The pacemaker is made by combining a CMOS circuit with monolithic integralted circuits into a hybrid circuit, which is characterized by low dissipation, light weight and small size.

本文介绍一种新型起搏系统——参数可调的埋藏式起搏器——的设计方案及实施技术.它由一个体外操纵器及一只带有数字记忆(由CMOS电路组成)元件的埋藏式起搏器所组成.无论在起搏器埋植前或后,当需要调节参数(包括接通或关断电源)时,可使用体外操纵器向起搏器发射一组编码的磁脉冲,这组脉冲被埋藏式起搏器感受,记忆,从而控制起搏参数到一新的指定的状态,并将这种状态一直保持下去直到进行再次调节. 由CMOS电路及混合型集成电路组成的起搏器具有功耗低、体积小、重量轻的特点.十个月的临床应用表明:调节灵活,性能可靠,疗效良好.

本文比较几个抽头加权值个数较少的13位巴克码脉冲压缩旁辦抑制滤波器的性能。计算结果表明,它们的主辦下降、主瓣展宽和信噪比损失相差不大。在小的多普勒频率范围内,复杂滤波器能把最大旁瓣以及均方旁瓣抑制到较低水平,但当多普勒频率增大时,这种优势逐渐消失,並转为劣势。
