摘要： A system computing the distance of a reflecting object from the position of an echo pulse within a range gate or telemetering window includes, as the second one of two cascaded integrators, an incrementor for converting the output voltage of the first integrator into a train of counting pulses with a cadence proportional to speed, these counting pulses being fed to a distance register which is periodically discharged into a countdown register to provide a pulse count proportional to distance. The countdown register is progressively read out by clock pulses over a period beginning with the emission of a highfrequency burst by the radar transmitter and ending upon the attainment of a zero count, or possibly a negative count establishing the lower limit of a range gate, as determined by an associated decoder controlling the telemetering-window generator. The output voltage of the decoder may be used to ascertain, with the aid of a comparator receiving a fixed reference voltage, the instant when a craft equipped with the radar system approaches a target to within a critical distance whereupon the first integrator is disconnected from the radar receiver to operate as a speed memory on the basis of data previously stored therein; the decoder output then continues its decrease, by extrapolation, in accordance with the diminishing target distance until another comparator gives rise to a firing pulse detonating a charge aboard the craft.

摘要： A visual display device for radar systems comprises a panel including a plurality of juxtaposed light indicators, each such indicator being formed by one or more lamps, and means for selectively operating the light indicators as a function of the position(s) of one or more detected targets in the area being scanned by the radar. The display device has two modes of operation : a first mode of operation (watch mode) in which the plurality of indicators is associated to the whole of the area being scanned and a second or ''''precise locating mode'''' of operation in which the plurality of indicators is associated to a portion only of the area being scanned thereby taking full advantage of the power of resolution and discrimination of the radar system.
