Title: Small ground-to-ground missile - has multiple detector including IR, seismic or magnetic sensors for guidance in triple phase trajectory
IPC: F42C13/00
Filed: 1968-09-18
Granted: 1980-07-25
Abstract: The small ground-to-ground missile is intended for anti-tank use has three distinct phases in its trajectory. The first stage (t1) is the ascent following initial firing, and this is followed (tf) by some braking, and a third stage (t2) which is the ballistic descent. The firing of the missile and its orientation is controlled by a multi-detector sensing and locating the target. The braking is controlled either by a retro-rocket, or by a parachute which is deployed at a predetermined height (h). The final phase is controlled by a further rocket which ends the braking motion. Propulsion is relatively simple, requiring only two charges detonated with a predetermined time delay between them. The multiple detector used for guidance may include infrared, seismic or magnetic sensors, or saturated core magnetometers whose outputs are electrically filtered.

The Specification describes control point based Doppler radar system for determining the spacings and/or traffic density of vehicles on a traffic way. The Doppler radar 1 illuminates vehicles on a route Y<SP>1</SP>-Y by means of a radio beam along axis X<SP>1</SP>-X. A Doppler frequency signal is produced by the radar as long as a vehicle is within the beam. A memory circuit 4 receives the Doppler signal and produces a signal of equal frequency which continues after the Doppler signal has finished. The output of the memory circuit is integrated in means 5 which is reset to zero by the start of the next vehicle Doppler signal. The count in means 5 when it is reset represents the spacing between the adjacent vehicles causing the relevant Doppler signals. Means 6 can indicate the spacing, give a " too close " alarm or be used in supervising the density of the traffic. The signal resetting the integrator 5 may be given after N vehicles have passed (Fig. 2, not shown), whence the output of the integrator represents the traffic density based on the space occupied by N vehicles.
