摘要： A method and apparatus for determining from a moving observer the location, in terms of latitude, longitude, altitude, and velocity, of a stationary or moving radar emitting a pulsed or continuous-wave signal. The moving observer extracts from the radar signal significant electronic support measures (ESM) parameters, including frequency, pulse repetition interval, and pulse width, and determines from those parameters whether a radio frequency (RF) or pulse repetition frequency (PRF) measurement technique is appropriate, and whether the radar signal angle-of-arrival (AOA) must be computed. The emitter location is computed using a ratio of sequential frequency measurements, and the moving observer continues to collect frequency measurements until the location of the emitter can be established to within a predetermined degree of certainty.

摘要： The present invention uses feedback 300 from RF carrier frequency measurements 301 to disassociate the emitter angle-of-arrival component 313 in the ambiguous phase measurement 312 from the initially unknown phase measurement integer ambiguities 314; to then process 302 resolve the ambiguities; and finally to process 303 to obtain the correct emitter AOA. The present invention does this by converting the actual interferometer baselines 315 on which the unassociated pulse 308 phase measurements 304 were made at different emitter frequencies to a baseline set 305 for a single-frequency equivalent interferometer array. This conceptual array has the following property: the phase measurement 306 that would be made on it at the fixed frequency for a signal at the same direction-of-arrival 307 are identical to the actual phase measurements made on the physical array. Because of this equivalency the conceptual array is called the E(equivalent)-array. But, whereas the physical array has antenna spacings 317 that are invariant, the E-array “antenna” spacings 316 change as a function of the RF carrier frequency measurement feedback 300, which depends on the particular residual pulses being tested. Thus there is a different E-array, even for the same frequency agile emitter, depending on the particular residual pulse set 309 used.

摘要： A method and system for determining the geolocation--i.e., the latitude, longitude, and altitude--of a stationary RF signal emitter from two or more moving observer aircraft. The observers receive signals from the emitter and the system measures the phase difference between the signals. The observers then perform pulse time of arrival (TOA) measurements over a predetermined clock interval, and calculate the time difference of arrival (TDOA) of corresponding, same-pulse, emitter signals. Based on geometric relationships, the system creates a series of circular lines of position (LOPs) for each observer, and computes hyperbolic LOPs based on the TDOA calculations. The system determines emitter location from the intersection of the hyperbolic LOPs and the circular LOPs.

摘要： Method and apparatus for enabling a pulse echo radar to generate a false signal in both time and frequency based passive Doppler ESM location systems. The latter false signal causes the ESM system to mislocate the radar. The radar's reference oscillator frequency is varied to create false passive Doppler information at an intercept receiver. These variations are predetermined changes in RF and PRF frequencies for the radar and are relatively small compared to those frequencies.

摘要： A method for determining a constant classification parameter for a radar is described; this parameter uniquely characterizes and identifies the radar being monitored. The method does not require the use of navigation or orientation information concerning the observer platform. The emitter pulse repetition frequency (PRF) provides a clock signal to allow measurement of the number of cycles of emitter carrier occurring in a predetermined interval. This value is the same at the emitter and at the observer and forms the aforementioned classification parameter. The classification parameter is additionally used to detect the presence of countermeasures designed to defeat passive Doppler emitter location.

摘要： An Angle of Arrival/Long Baseline Interferometer (AOA/LBI) passive ranging apparatus and method for emitter range determination can use any convenient airframe location for the two-antenna uncalibrated LBI baseline. This baseline has a theoretically unlimited length and does not require a specific SBI/LBI baseline ratio. Only a single initial AOA is required. Range partitions are formed along the single AOA. The emitter is assumed to lie in any of N range bins and the corresponding DOA (direction of arrival) unit vectors computed. Each of these DOA unit vectors is then used to predict the LBI phase differential and the N resolved LBI phases each drive a location estimator. The location estimator (filter) with consistent output provide the emitter range. The LBI range from these filters is used for subsequent DOA generation and ambiguity resolution.
