Title: Radar systems
IPC: G01S13/10
Filed: 1973-11-13
Abstract: 1424026 Pulse radar MARCONI CO Ltd 5 Sept 1974 [13 Nov 1973] 52548/73 Heading H4D A radar system comprises a transmitter for transmitting two consecutive radar pulses, which are separated by a predetermined time, and which differ in that one only is frequency swept. The system further comprises a receiver having two channels, one for processing non-swept pulses and providing signals indicative of targets within a first range zone, and the other for processing swept pulses and providing pulse compressed signals indicative of targets within a second range zone. As described, the transmitter transmits a short non-swept pulse (of duration, typically, 50 nano-seconds) followed after an interval of time tl by a frequency swept pulse of duration t2. The non-swept pulse is used for the detection of targets with, say, 10 km. of the system, and the swept pulse is used for the detection of targets beyond this range and up to a predetermined maximum range, and the times t1, t2 are determined accordingly. At the receiver the return signals from targets are applied to the paralleled inputs of two gates 3, 6 after being processed in R.F. amplifying and mixing stages 1, and in an I.F. amplifier 2. A signal from a synchronizing unit to the control terminal 14 of the gate 3 opens it for a time t3#t1, during which non-swept pulse return signals are passed to a detector 4. Following closure of the gate 3, the frequency swept pulse is transmitted and, after allowing sufficient time for returns from targets within the first range zone to pass, the gate 6 is opened by a signal to its control terminal 15. Swept pulse return signals pass via a weighting amplifier 7 to a dispenser 8, where they are compressed, and thence to a detector 9. In order that the outputs from the detectors 4 and 9 may be displayed together, those from the former are delayed by a time which is, nominally, t1+t2, in a unit 5, and are then combined with those from the latter in a summing circuit 10.

In Figs. 1, 2 and 3 the air flotation clarifier tank (4) is surrounded by an annulus (6) forming the gravity clarifier tank. The influent enters by a conduit (14) with holes (14'). Sludge is raked from the bottom of tank (6) by a rake (28) fitted with a blade (32) on framework (34). The bridge (36) supporting the scraper may be moved between the limits 58 and 60. Scum is removed by the skimmer blades (82) (83) also connected to the frame work (34). The liquid flows from tank (6) through a launder (64) and is divided by a weir plate (68).
