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.

Radar system and method

A radar system comprising a transmitter to transmit radar signals into a region, a receiver to receive return signals of said radar signals reflected from within the region wherein the transmitter and receiver are adapted for location on a structure at a wind farm, and a processor to process the return signals to extract wind farm associated data for said region.

Radar system

A method of classifying items from reflected signals returned from said items is disclosed, the method comprising: processing said return signals to discriminate between a first set of signals indicative of items of interest and a further set of signals indicative of clutter; identifying items from said first set of signals and classifying them as a first class of item; processing said further set of signals to identify a second set of signals indicative of further items of interest; identifying items from said second set of signals and classifying them as a second class of item.

Adaptive radar

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.

Determining positional information

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.

Methods and apparatus for obtaining positional information

A vehicle ( ) such as a motor road vehicle is fitted with an electromagnetic sensor system comprising transmitting means (e.g. ) for transmitting a radio frequency signal, receiving means (e.g. ) for receiving reflections of said signal from remote objects, sampling means ( ) operable to sample the received reflected signal (or a signal derived therefrom), and processing means (e.g. ) 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. ) 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.

Electromagnetic sensor system

A radar system adapted to be installed on a vehicle (,) is operable to detect objects in different fields of view of the system. The system has transceiver means (,) 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 (,) 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. Such alterations are carried out under the control of control means which is connected to sensor means for detecting a property of the operation of the vehicle, determining a required position of the field of view, and setting the field of view of the system accordingly. The range shell positions, and hence fields of view, can also be changed by selecting alternative transmitters and/or receivers of the transceiver means. There is also shown a motor road vehicle which has a radar system comprising a pair of transmitter antennas at two alternate corner regions of the vehicle and a pair of cooperating receiver antennas of the other two corner regions. Certain embodiments of the system also have the facility to generate range shells which are swept over an area around the vehicle or which track detected objects.
