1. A tracking system for predicting the incidence of threat signals having at least one beam at a predetermined location in space, said system comprising:
- a receiver for detecting the incidence of the threat signals;
a tracker that cooperates with said receiver to predict the detection of a threat signal by the receiver; and
a controller that condenses threat signals from harmonically related beams of a pulse group detected by the receiver in response to a command signal from said controller, and that controls the predictions of said tracker in response to characteristics of the condensed threat signals.

Abstract
A tracking system for predicting the incidence of threat signals having at least one beam at a predetermined location in space in which a receiver detects the incidence of the threat signals at the predetermined location, a tracker cooperates with the receiver to predict the detection of threat signals by the receiver, and a controller condenses threat signals from harmonically related beams of a pulse group detected by the receiver and controls the predictions of the tracker in response to the characteristics of the condensed threat signals.

2. A method for detecting radar threat signals, said method comprising the steps of:
-
detecting a group of radar beams having predetermined radar transmission characteristics; and condensing at least one subgroup of pulses which have substantially equivalent carrier frequency and harmonically related pulse repetition intervals from the detected group of radar beams to detect at least one threat signal having a plurality of pulse stagger levels with at least one pulse repetition interval nonidentical to the others. - View Dependent Claims (3)

- 4. A threat signal radar detection system including a radar receiver for receiving radar beams constituting a plurality of threat signals, said system comprising a controller for condensing from said received radar beams at least one group of pulses which have substantially equivalent carrier frequency content and harmonically related pulse repetition intervals to detect at least one threat signal, having a plurality of pulse stagger levels with at least one pulse repetition interval being nonidentical to the others, from the plurality of received threat signals.
