High-precision radiometric calibration and synchronization compensation must be provided for distributed radar system due to separate transmitters and receivers. This paper proposes a transponder-aided joint radiometric calibration, motion compensation and synchronization for distributed radar remote sensing. As the transponder signal can be separated from the normal radar returns, it is used t...

Bistatic radar systems will play a great role in the coming decade since a large number of radar missions are being foreseen. Using existing transmitters, formations of small passive receivers will enhance our capability to gather backscatter information from earth. A bistatic SAR system operates with separated transmitting and receiving antenna and both can follow independent trajectories. If ...

Continuing advances in radar technology are driven both by new application regimes and technological innovations. A family of applications of increasing importance is detection of a mobile target intruding into a protected area, and one type of radar system architecture potentially well suited to this type of application entails a network of cooperating radars. In this paper, we study optimal r...

This paper describes a 24GHz CMOS RF transceiver for car radar applications. The transceiver consists of 4-channel receiver array and 1-channel transmitter. The prototype is designed by standard RF CMOS 0.13-μm technology. The simulated receiver gain is 30dB and simulated tramsmitted output power is 15dBm at 24GHz.

There are many proposals for multi-channel radar, emanating from the conventional monostatic radar system where transmitter and receiver are collocated. Collocation makes it easy for transmitter and receiver to share a common stable clock (local oscillator), which is required for both range and Doppler measurements. Signal processing for multi-static radars (see [1]) with widely dispersed anten...

in ultra-wideband (uwb) multistatic microwave breast cancer imaging, the long imaging time is an important issue. in this paper, a novel imaging method for multistatic uwb radarbased microwave breast cancer imaging using sparse sampling has been proposed that significantly reduces the amount of data and imaging time. in this method, instead of measuring multistatic radar signals conventionally,...
