摘要： Threshold circuit for selecting video signals derived from small stationary and moving objects amidst an abundance of clutter in a harbor area. The threshold voltage generator (1) of this circuit is suitable for detecting the temporal average .DELTA.P of the positive peak value and the temporal average .DELTA.N of the negative peak value from the AC component of the applied video voltage (V.sub.DC +V.sub.AC) and for generating modified voltages (l+k)(V.sub.AC -.DELTA.P) and k(-V.sub.AC -.DELTA.N). The modified voltages together with the inverted video voltage are combined to form the threshold voltage V=V.sub.DC +.DELTA.P+k(.DELTA.P+.DELTA.N) being k times the average peak-peak value above the average peak value of the video voltage, where k is a constant.

摘要： To simulate the radar return from terrain of particular generic type (e.g. desert, forest, cultivated land) it is a known suggestion to employ closed-loop shift register with feedback suitable to produce particular "texture" of return from specified terrain. It is here disclosed to synchronize output of such register with azimuthal position of simulated search radar; but this alone gives "grainy" effect because "smeary" or slowly changing amplitude with range in PPI sweep is not matched by corresponding lateral, or azimuthal, "smear". This objectionable effect is overcome by providing three sets of output terminals on feedback register, giving outputs corresponding to shifts for azimuths N, N+1, and N+2. By buffing together the three outputs, an azimuthal variation at a slow rate, comparable with the variation with range, is obtained, giving a more deceptive (and thus better) simulation.
摘要翻译：为了模拟特定通用类型（例如沙漠，森林，耕地）的地形的雷达回波，已知的建议是采用具有反馈的闭环移位寄存器，该反馈适用于产生特定地形的特定“纹理”。这里公开了将这种寄存器的输出与模拟搜索雷达的方位位置同步; 但是由于PPI扫描中的“smeary”或者随范围缓慢变化的幅度与相应的横向或方位角“涂片”不匹配，所以会产生“粒状”效应。通过在反馈寄存器上提供三组输出端子来克服这个令人反感的效果，给出对应于方位N，N + 1和N + 2的移位的输出。通过将三个输出结合在一起，获得与变化范围相当的慢速方位角变化，给出更具欺骗性（因此更好）的模拟。

摘要： An intruder detection transceiver in which close-in sensitivity is reduced or eliminated to alleviate false alarm problems. An ultrasonic or microwave transceiver contains a transmitter and receiver for transmitting and receiving signals for intruder detection. By mounting the transmitter and receiver at the proper angle with respect to each other, close in sensitivity is reduced without materially affecting sensitivity at greater distances.

摘要： A system for the surveillance of a route along which vehicles are moving, and which operates in real time, comprises radar equipment whose transmitter and receiver are each connected to a leak line acting as an antenna for respectively transmitting outgoing energy from the radar unit and conveying reflected energy back to the radar unit. These lines are mutually decoupled so that only the line connected to the receiver picks up the energy reflected by a moving object or a fixed obstacle situated on the surveyed route.

摘要： An electromechanical transducer is provided for producing pulses of sonic energy and respondingly generating electrical signals relative to received sonic energy wherein a driver generates the sonic pulses; and an improvement for projecting the sonic energy in a peculiar controlled pattern is a wave guide interposed at the output of the driver for controlling the propagation of the pulses by setting up substantially a line source of sonic energy which emanates the sonic energy in an operating pattern of at least a minimum intensity near the point of greatest breadth of the pattern. There has been provided an electromechanical transducer for projecting sonic energy in a peculiar pattern including a head mounted at the output of the transducer and a wave guide having a transverse slot therethrough adapted to cooperate with the head for directing the propagation of the sonic energy to substantially complete sonic coverage within a limited range.

摘要： In a radar installation or the like, incoming multidigit signals are registered in a memory having as many stages as there are digital positions in a signal. In order to discriminate against parasitic signals, correspondingly positioned digits of an incoming signal and a preceding signal already registered in the memory are compared; to compensate, however, for unavoidable delays in the registration of each incoming digit, the digits of the preceding signal are read out from memory stages that are staggered with reference to the stages in which the incoming digits are concurrently inscribed, the offset between the inscribed and the readout stages being equal to M
