  • Publication number: 20170082732
    Abstract: A radar system for discriminating between sources of radar interference and targets of interest. The system includes a transmitter for transmitting radar signals into a region, a receiver for receiving return signals of the radar signals returned from within the region, and a processor for processing the return signals to discriminate between return signals returned from a first object and return signals returned from a second object where the return signals from the second object comprise both zero and non-zero Doppler components and interfere with the return signals from the first object. The radar system is operable for discriminating between the return signals when the return signals are received at a distance from the second object which is less than a proximity limit based on the geometry of the object.

  • Publication number: 20130127656
    Abstract: A method of filtering radar return signals to discriminate between targets of interest and clutter is presented in which a filter filters radar return signals received by a first radar receiver, based on radar return signals received at another radar receiver, to produce filtered radar return data in which radar return signals received by the first radar receiver for targets of interest are present and radar return signals received by the first radar receiver but arising from clutter are suppressed.

  • Patent number: 7750841
    Abstract: Apparatus for determining positional information relating to an object, comprising: means for receiving, comprising a plurality of receiving elements; detection means for detecting signals received at the receiving elements and for generating output signals representative of the received signals; and processing means operable to apply, for each receiving element, a process to the output signal generated from the signal received at that receiving element separately from any output signal generated from a signal received at any other receiving element, so as to obtain a respective value of a parameter representative of the signal received at that receiving element, the processing means being further operable to compare the values of the parameter thus obtained so as to, obtain positional information relating to the object.

  • Patent number: 7227493
    Abstract: An apparatus and method obtains positional information about one or more objects in a detection field. An array includes a transmitting element and a plurality of receiving elements. A truncated cross-correlation function may be applied to determine the interval between signals received by a plurality of the receiving elements, thereby to determine an angular position of an object. A warning zone may be defined and it is determined whether an object is within the warning zone. Also disclosed are techniques for stretching received signals, and techniques for obtaining positional information relating to an object using non-Doppler radar.

  • Patent number: 6411250
    Abstract: A vehicle (160) such as a motor road vehicle is fitted with an electromagnetic sensor system comprising transmitting means (e.g. 4, 1) for transmitting a radio frequency signal, receiving means (e.g. 2, 6) for receiving reflections of said signal from remote objects, sampling means (20, 28) operable to sample the received reflected signal (or a signal derived therefrom), and processing means (e.g. 36) for processing the sampled signal, and operable to detect said reflections in the sampled signal, and to determine information on the presence, position and/or range of said object. The system includes filter means (e.g. 34) for preventing radio signals transmitted by other sources or noise spikes from causing interference which results in spurious detections or indications of range by the processing means.

  • Patent number: 6215438
    Abstract: A radar system adapted to be installed on a vehicle (1) is operable to detect objects in different fields of view of the system. The system has transceiver means (2, 3; 44, 46) for transmitting a radar signal and receiving the signal after the latter has been reflected from an object to be detected. A reflected signal is sampled by sampling means (12; 66) during a succession of sampling periods each of which is delayed with respect to a corresponding portion of the transmitted signal. The gating of the reflected signal effectively generates range shells, each of which corresponds to the time taken for a transmitted signal to reach an object at the shell, and to be reflected back to the system and is hence related to the delay between the transmission of the signal and the corresponding sampling period. The range shells define the field of view of the system, which can be changed by altering said delay.

  • Patent number: 5734346
    Abstract: A method of detecting the displacement of a target in a given environment includes storing reference data having data representative of the environment; transmitting a transmit signal towards the target; sensing the return signals from the target and the environment; and detecting the displacement of the target by comparing the return signals and the stored reference data. A method of detecting the level of a sample in a container is also disclosed. Analogous apparatus features are also disclosed.
