Title: Synthetic array auto-focus control for radar system - derives focus error from three sub-arrays with bisector of two outer sub-arrays resultants in phase with resultant of centre sub-array
Inventor: HERMAN ELVIN E
IPC: G01S13/90
Filed: 1977-08-09
Abstract: The auto focus system uses focus error data derived by dividing the synthetic array into three sub-arrays. The resultant outputs are processed together to extract data corresponding to the degree of total array defocus. For purposes of imagery generation, the phase and amplitudes of these three sub-array resultants are vectorially summed together and the resultant is magnitude detected to yield imagery output corresponding to the full synthetic array. For derivation of focus error data, the mean bisector of the relative phase angle between the two end sub-array resultant vectors is measured. This derived phase angle is compared to the phase angle of the central sub-array resultant vector. The angle of the bisector relative to the central sub-array resultant is representative of the degree of defocus, and the sign of the angle is indicative of whether the array is over or under-defocused.

Title: Harmonic analyser for periodic functions - involves multiplication of function by sine-wave of predetermined frequency, and measuring phase angle
Inventor: NAEBAUER ANTON
IPC: G01R23/16
Filed: 1977-08-27
Abstract: The harmonic analyser comprises an automatic voltage regulator (AVR) to which the input signal is fed.

The multiplier also derives an input from the output of the voltage-controlled phase-shift stage (VCP). The latter is driven from a phase control oscillator. The phase angle between the fundamental and the harmonic is measured by an integrator operating as an operational transductance amplifier.

IPC: H03J1/04
Filed: 1978-12-23
Abstract: The radio receiver has oscillators assigned to its individual frequency ranges whose outputs are mixed with the received signals and whose outputs are passed to switchable stages of a frequency divider for frequency measurement. Each divider stage only receives the output signals of that oscillation belonging to the switched-in frequency. The output signals of the oscillator belonging to the switched-in frequency range are passed to the divider after a delay. The signal path between the oscillators and the divider stages is interrupted or short circuited during this delay.
