Implementation of Noise Radar Technology in Ground Based SAR for Short Range Applications
2007 International Kharkiv Symposium Physics and Engrg. of Millimeter and Sub-Millimeter Waves (MSMW), 2007In this paper, results of implementation of noise radar technology in X-band narrowband ground based (GB) synthetic aperture radar (SAR) were presented. The radars under consideration use noise waveform (NW) as a probe signal and perform the range focusing by correlating the radar returns with a reference signal taken before transmission, while the way

Differential Low Noise Amplifier for S-Band Phased-Array Radar in 0.18-µm CMOS Technology
2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019An S-band differential low noise amplifier (DLNA) is presented and implemented in TSMC 0.18-µm CMOS process for use in the receiver of a phased-array radar. A special layout approach is used in the input matching circuit by integrating two individual inductors together to shrink the chip area while increasing the inductances. The 3-dB gain bandwidth of

2017 18th International Radar Symposium (IRS), 2017
The results on the use of arbitrary waveform generators that are based on FPGA technology for generation of complex signals in modern noise radars are presented. On the basis of these devices we propose a radar scheme with digital generation of noise waveforms for both sounding signal and reference and analog processing.

A 9 dB Noise Figure Fully Integrated 79 GHz Automotive Radar Receiver in 40 nm CMOS Technology
2019 IEEE Radio Frequency Integrated Circuits Symposium (RFIC), 2019This paper presents a low noise and fully integrated automotive radar receiver in 40 nm CMOS technology. The receiver adopts the direct conversion architecture, and it consists of a low noise amplifier (LNA), mixer, and analog baseband blocks. The three-stage LNA and the low noise mixer improve the whole receiver noise figure (NF).

The well-known classical pulse radar has several disadvantages. The high transmitted peak power can be easily detected and warn an enemy, and the ambiguities in both range and Doppler measurements lead to problems with unambiguous localization and tracking.
