提出了一种步进式多频中断连续波雷达多目标检测系统。与传统的上/下扫FMCW相比，所提出的系统可以获得较短的观测时间（调频连续波）系统或双频连续波系统，其计算复杂度比二维超分辨系统低，通过使用用于短程目标的新的发射频率序列和单维超分辨系统，分辨率系统，其通过使用普通傅立叶变换来预处理目标速度检测处理。此外，所提出的系统可以获得所需的目标距离和速度分辨率的传输频率带宽小于脉冲压缩系统或FMCW系统。所提出的系统还可以避免导致FMCW系统问题的配对故障。还可以获得多个等速目标的距离分离，这是双频连续波系统中的一个主要问题。计算机仿真表明，作为一种雷达系统，该系统有望改善上述问题的传统雷达系统在实际输入SN值。© 2007 Wiley Periodicals，Inc.

This paper proposes a multiple target detection system using stepped multiple frequency ICW (Interrupted Continuous Wave) radar. The proposed system can obtain a short observation time compared to a conventional up/down sweep FMCW (Frequency-Modulated Continuous Wave) system or a two-frequency CW system with less computational complexity than a two-dimensional super-resolution system by using a new transmission frequency sequence intended for short-range targets and a single-dimension super-resolution system that preprocesses a target velocity detection process through the use of an ordinary Fourier transformation. In addition, the proposed system can obtain a desired target range and velocity resolution with a transmission frequency bandwidth less than a pulse compression system or an FMCW system. The proposed system can also avoid pairing malfunctions which lead to problems with FMCW systems. Range separation of multiple equal-velocity targets, a principal problem in two-frequency CW systems, can also be obtained. Computer simulations show that as a radar system, the proposed system is expected to improve the above-mentioned problems of conventional radar systems at practical input SN values. © 2007 Wiley Periodicals, Inc.
