<p>The present invention provides a method for separating, or de-interleaving, a stream of radar pulses, interleaved in time, received by a receiving antenna (10) and receiver (12) from several radar sources. De-interleaving the stream of received pulses may include forming clusters of pulses having similar parameter values around anchor points, where each cluster is defined by a window around its anchor point. The dimensions of each window may be determined by a weighted distance, i.e., a measure of dissimilarity, calculated using weights. Each weight may depend inversely on the measurement error in the parameter with which the weight is associated. Each anchor point may have a set of weights adjusted to its parameter values, and which may change as operating conditions change. The weights may be determined using a method including a calibration step, which may include injecting pulses with known parameters into the receiver (12).</p> |
