Abstract: A pulse description word (PDW) data preprocessing and detection method for modulation analysis in a pulse are disclosed. A lot of PDW data, which is generated by a channelized digital receiver with radar signals, is successively arranged according to the time of arrival (TOA). The PDW data which the TOA, a frequency, and a pulse width are overlapped is deleted. When the frequency is swept and the PDW data divided into a plurality of channels is generated, the PDW data is combined based on a set of sweep information and generation channel information. When the frequency is hopping and the PDW divided into the channels is generated, the PDW data is combined based on the information for the TOA and the pulse width. A PDW used for the modulation analysis in the pulse is selected based on a performance result. Optical PDW data capable of accurately recognizing the type of the modulation in the pulse corresponding to an importance identification variable is detected. The importance identification variable improves the radar signal identification ability of an electron source system.

Abstract: PURPOSE: A target location tracking device is provided to improve location tracking performance on a moving target by adaptively determining a noise parameter of a state model of a Kalman filter depending on the circumstances using a location measurement value of a measured target and location information of multiple separated receivers. CONSTITUTION: Multiple receivers(10) are spaced from one another, receive a radiation signal(S) from a target(T), and transmits a reception signal corresponding to the received signal to a control unit(20). The receivers transmit location information of each receiver to the control unit. The control unit consists of a measurement module, an initial value setting module, a noise parameter determination module, and a target location tracking module. The target measurement module measures a target location at a specific time using information such as TOA(Time of Arrival) and AOA(Angle of Arrival) of the received signal based on the location and target of the receiver. The initial value setting module sets up an initial value of a Kalman filter execution module, using an initial target location measurement value of the target or a predetermined value. The noise parameter determination module adaptively determines a noise parameter of a state module of the Kalman filter using the measured target location measurement value and the location information of the receiver whenever the location of the target is completely measured.

Abstract: A method of recognizing a radar intra-pulse modulation type by using a specific factor according to the present invention includes reading out I/Q (In-phase/Quadrature) information selected from pulse description word (PDW) to recognize an intra-pulse modulation type of a received/measured radar signal, and classifying the intra-pulse modulation type into non-modulation (NM), frequency shift keying (FSK), phase shift keying (PSK), linear frequency modulation (LFM) and non-linear frequency modulation (NLFM) by obtaining and using power spectrum density (PSD), an instantaneous frequency and a peak of a statistical test, so that the intra-pulse modulation type may be more exactly recognized from the specific factor. Thus, the information about an intra-pulse modulation type, which is an important factor for greatly increasing the capability of identifying a radar signal of an electronic warfare support system, may be more exactly obtained.
