Electronic radar sensors

Frank A. Horrigan retired from the technical development staff for sensors and electronic systems at Raytheon Systems Company. Dr. Horrigan has a background in technologies relevant to military systems, in particular, radar and sensor technologies. A theoretical physicist, he has more than 37 years experience in advanced electronics, electro-optics, and advanced information systems. In addition, he has experience in planning and managing industry research and... 

Monostatic antennas use the same focussing mechanism for the transmitted and the received signals, with the signal channels being separated electronically. Direction-sensitive decoupling between the transmitted and the received signals is required for the FMCW radar. As indicated in Fig. 7.7.3, this can be achieved with a circulator or with suitable directional coupler structures. Fig. 7.7.4 is a photograph of the Bosch 77 GHz sensor. 

Avionics and Navigation. Condensed from the term aviation electronics, the term avionics has come to include the generation of intelligent software systems and sensors to control unmanned aerial vehicles (UAVs), which may operate autonomously. Avionics also deals with various subsystems such as radar and communications, as well as navigation equipment, and is closely linked to the disciplines of flight dynamics, controls, and navigation.
