• Improved radar visibility of small targets in sea clutter

Publication Year: 1966, Page(s):135 - 147
Cited by:  Papers (5)
| | PDF (2027 KB)

An X-band radar has been built with an antenna capable of rotational speeds up to 1400 rev/min, and a display system which follows at these speeds. This enables only one or two pulses per beam-width to be displayed, the pulses received from successive looks at the sea clutter being de-correlated. A conventional fluoride p.p.i. tube and a storage p.p.i. tube were used simultaneously. The resulting ... View full abstract»

• A true i.f. logarithmic amplifier using twin-gain stages

Publication Year: 1966, Page(s):149 - 155
Cited by:  Papers (5)
| | PDF (682 KB)

A true i.f. logarithmic amplifier is described which avoids the successive detection principle and its associated video delay line. Each stage comprises a pair of long-tailed pairs in a complementary role. Transistors are used throughout but bottomingÂ¿ is avoided, and bandwidth variations are negligible. A dynamic range of about 100 dB is possible. A video output may be derived if desired from a... View full abstract»

• Antenna for rapid scan decorrelation radar

Publication Year: 1966, Page(s):156 - 158
| | PDF (629 KB)

The mechanical design of an X-band antenna suitable for rotational speeds up to 1400 rev/min is described. The microwave design and performance are briefly outlined. View full abstract»

• Design of parallel counters using the map method

Publication Year: 1966, Page(s):159 - 162
| | PDF (335 KB)

This paper describes how a counter may be designed to follow any desired code. The method is illustrated by the design of a parallel counter operating in the 5211 binary-coded decimal mode and which uses J-K flip-flops. The modules for the complete design are available as silicon integrated circuits. The minimized input conditions for a number of other coded decade counters are also stated. View full abstract»

• U.H.F. television reception with incident field strength of under ioo microvolts per metre

Publication Year: 1966, Page(s):163 - 164
| | PDF (505 KB)

Techniques in current use for the reception of the B.B.C.-2 programme at u.h.f. are illustrated, with reference to operational unmanned remote site installations. At u.h.f. an engineered receiving site can be designed for 20 dB better signal/noise ratio than is practicable and economic on domestic television installations View full abstract»

• A fast off-line digital correlator using magnetic tape for storage, repetition and scanning

Publication Year: 1966, Page(s):169 - 185
| | PDF (1884 KB)

Special purpose digital apparatus is described for off-line correlation of time varying functions in analogue form. The necessary storage, repetition and relative scanning are afforded by an instrumentation magnetic tape recorder through the extension of its closed loopÂ¿. A new value of lag coincides with the complete replacement of that length of tape contained within the `closed loopÂ¿, and a ... View full abstract»

• A three-cavity refractometer and associated telemetry equipment

Publication Year: 1966, Page(s):186 - 190
| | PDF (876 KB)

The paper describes the construction and performance of a microwave, spaced-cavity refractometer designed for the measurement of the small-scale variations of refractive index in the lower atmosphere. The instrument has been used on a captive balloon at heights up to 2Â¿5 km with telemetry equipment transmitting, to a ground station, information on variations in refractive index, temperature, wind...

• A transistor-diode feedback type logic circuit

Publication Year: 1966, Page(s):191 - 199
| | PDF (1166 KB)

The paper describes an improved form of saturated transistor logic circuit in which rectifier diodes are used to provide non-linear current feedback from collector to base of the transistor. The resulting arrangement has many advantages over the basic saturated circuit, particularly with respect to speed and logical versatility. Due to the ability of the circuit to handle two levels of logic in ea... View full abstract»

Aims & Scope

Published from 1963 to February 1964 by the British Institution of Radio Engineers and from March 1964 to 1984 by the the Institution of Electronic and Radio Engineers, The Radio and Electronic Engineer published papers describing original research and development in all branches of electronic engineering, as well as critical and interpretive surveys.
