2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
This paper describes a fully-integrated 77-GHz distant-selective pseudo-random noise coded Doppler radar transceiver in a Silicon-Germanium technology. The transceiver is capable of measuring a vibration or a velocity of a target at a specified distance, which is programmable and can be configured very precisely in the transceiver, and suppressing all ...

2004 IEE Radio Frequency Integrated Circuits (RFIC) Systems. Digest of Papers, 2004
An active down-conversion mixer for automotive radar applications at 76 GHz to 81 GHz was realized in a 200 GHz f/sub T/ SiGe bipolar technology. A conversion gain of more than 24 dB and a single-sideband noise figure of less than 14 dB is achieved. The 1 dB output compression point is -4 dBm. The power consumption is 300 mW at -5 V supply voltage.

2013 IEEE Asian Solid-State Circuits Conference (A-SSCC), 2013
A low phase noise 24/77 GHz dual-band subsampling PLL with a dual-band VCO is presented. Implemented in 65 nm CMOS technology, the proposed PLL occupies an area of 900 μm × 550 μm. The measured phase noise is -120.0 and -108.5 dBc/Hz at 1 MHz offset in 24 and 77 GHz modes respectively. With 1.3 V supply, the power consumption is 26.4 and 31.5 mW for 24

Time-frequency, bi-frequency detector analysis of noise technology radar
2012Enemy integrated air defense systems (IADS) using low probability of intercept (LPI) emitters can cause significant problems for suppression of enemy air defense (SEAD) techniques. New threat emitter configurations using low-power random noise modulation have a significant processing gain unavailable to non-cooperative intercept receivers. Consequently,
