In this paper, a system on programmable chip (SoPC) based implementation of digital receiver for monopulse tracking radar applications applying linear frequency modulation (LFM) signal is given. In order to meet the increased requirements of system miniaturization and low power consumption, the system function will be partitioned into several time-division stages with software or hardware implementation ways respectively, and an optimized processing structure in field programmable gate array (FPGA) is proposed to integrate all the processing procedure into single FPGA chip. In the verification part, the field experimental results indicate the validity of the system design and engineering applicability of the proposed structure. [ABSTRACT FROM PUBLISHER]

Signal processor is a key part for radar seeker. In this paper, a missile-borne monopulse radar signal processor is porposed and described. According to the requirement of monopules radar, a signal processor with better commonality and versatility is designed with a FPGA&DSP structure. Firstly, some related signal processing theories are reviewed and the implementation techniques in engineering are analyzed. Secondly, the hardware realization of the signal processor is presented. Finally, some measurements and compensation for the signal processor are implemented, and the results indicate that the design of the signal processor is successful. [ABSTRACT FROM PUBLISHER]

A new long-distance microwave reading system is introduced, that we shall call RID (Remotely Identify and Detect), able to locate and identify objects in harsh indoor environments. This is obtained by augmenting standard RFID reader operations with the mono-pulse RADAR principle and electronic beam scanning capabilities. In this way reading failures due to operation in severe fading environments are effectively overcome. The technique is experimented at 2.45 GHz and may be frequency-scalable: the higher the operating frequency the closer can be the tags to be detected. The system is realized by a suitable combination of custom designed components, such as a double printed-monopole array with electronic scanning capability, and of low-power commercial transceivers and MCUs. This results in an handheld low cost device with total dimensions comparable with typical PDAs. The system capabilities are demonstrated in indoor scenarios locating and selecting closely-spaced tagged items, fixed or moving. From this view point RID could be an answer to the intense research and industrial interest solicited by the needs of interacting with systems of devices, such as sensors and actuators, capable of improving the living conditions both at home and in a work space.
