Title: Improvements in or relating to radars
Inventor: WOOD JOHN RICHARD MARK PETER J
IPC: G01S13/44
Filed: 1969-04-17
Abstract: 1285053 Monopulse radar MARCONI CO Ltd 26 Nov 1969 [17 April 1969] 19601/69 Heading H4D A monopulse radar has an auxiliary waveguide located centrally of the radiating horns or waveguides of the static split aerial system for injecting auxiliary signals, of the same frequency as the radar operating frequency into the aerial receiving channels, which signals represent a target situated on the mechanical axis of the aerial and also has means for using the signals produced by the radar in response to the auxiliary signals, as error correcting signals when receiving echoes from a target. In a normal monopulse radar system the four signals from a square cluster of elements in the aerial 1 are combined by hybrid system 4 to produce a sum and azimuth and elevation difference signals. These signals are fed to receiver 6 where they are converted to I.F. The I.F. signals are then passed to three amplifiers 51, 71, 81 which are gain controlled by a voltage dependent on the detected amplitude of the sum signal. The difference signals are then compared to the sum signal in two phase sensitive detectors 10, 11. The auxiliary signals are injected into the radar from a waveguide (W) connected to the output of a variable h.f. source 12, which may be part of the radar transmitter 2. A switch 13 causes the signals to be injected and also operates a magnetic tape or other recorder 14 which records the outputs from the two PSD's due to the injected signals. These values are then fed into two subtractors 15, 16 the other inputs to which are the P.S.D. outputs. When echoes from a target are received, they are processed normally and the outputs from the subtractors 15, 16 are thus corrected by the error signals from the recorder. The subtractor outputs are used to control the aerial to track the target or are fed to a display. The use of this system allows different errors e.g. due to using different operating frequencies and ageing of components or temperature effects to be allowed for. If a four horn aerial is used the auxiliary signals are injected through coupling holes in the four horns (H) and in the waveguide (W) positioned centrally of the cluster (Fig. 2, not shown). If a two element aerial is used the coupling holes are arranged to be in the parallel sided sections of the horns (Fig. 3, not shown) or in the waveguide feeders to the horns (Fig. 4, not shown) not in the flared portions.

Abstract: 1510657 Measuring outlines photo-electrically NIPPON KOGAKU KK 14 May 1975 [14 May 1974] 20392/75 Heading G1A Apparatus for measuring the contour length of a two-dimensional pattern comprises: means for scanning the pattern and sampling each scanned line at predetermined sample intervals; means for providing digital signals related to line segments of the scanned pattern; means for classifying line segments as integral multiples of the sampling interval; means for summing the lengths of the line segments; means for providing relative rotation between the pattern and the scanning field; and means for determining the average of the contour lengths measured at several angular positions. Signals from a TV camera 2 Fig. 3A, scanning a pattern T temporarily stationary on a turn-table 1, are sampled at intervals a during each line scan to provide signals defining horizontal segments ia (i an integer) and vertical segments b of a rectangular approximation to the pattern illustrated in Fig. 1. The top line, for example, intercepts a segment N5 of length 5a; that part of the second line which is not overlapped by the top line, defines a segment N4; and so on. Where two adjacent lines start or finish together they define between them a vertical segment No of height b. It is shown that, provided the orientations of the outline segments of the actual pattern are randomly distributed, the lengths of all outline segments intercepted by scanning line segments longer than 3a may be approximated by the simple multiple ia to better then 1%. The random distribution is obtained by repeated measurements on the pattern at different angular positions, which may be obtained by rotating the turn-table 1 as shown, or by rotating an inverting prism (35), Fig. 4 (not shown). The apparatus Fig. 3 includes edge detectors 6, 7, 13, 14, 15; a one-line memory 5 for delaying a line SN to compare it with a following line SN+1; an AND gate for detecting when two lines start or finish together (defining an No segment); and an exclusive -OR gate 9 for detecting when at least part of a line is not overlapped (defining a horizontal segment). Vertical segments are counted in a counter 28. Horizontal segments are routed to counters 29, 30, 31 if their lengths are found to be a, 2a or 3a. All segments exceeding 3a are summed in an adder 32 and stored in an M register 33. The outputs from the counters 28-31, weighted by predetermined coefficients, and the output from the register 33, are further processed and combined in a computer 34.
