    In a complex electromagnetic environment, the measurements obtained by passive radar are usually uncertain due to the influence of many factors such as noise, interference and missed detection. The selection of the measurement model depends on the target state, which affects the implementation and performance of the tracking algorithm and may result in the trajectory tracking diverges under serious cases. Aiming at this problem, a measurement model based on passive bistatic radar is first established. Then the impact of the bistatic and cartesian measurement models on the tracking performance of different types of targets is investigated in combination with simulations. Finally, the performance of the two measurement models is confirmed via real data processing.

    In order to solve the problem of the aerial defense system in detecting stealth targets,a new method is presented which combines near space operating area with receiving/transmitting mechanism,i.e.,a bistatic radar system based on the near space operational platform.Taking F-117A model as example,the bistatic radar RCS is simulated with the electromagnetism software in the C waveband.The detection range of the near space bistatic radar to anti-stealth is simulated based on the new gridding analysis method.The effect of the method is compared with the detection ranges of the monostatic radar and ground-based bistatic radar,and the advantages of the near-space based bistatic radar in detecting stealth targets are validated.The application prospect of it in the future aerial defense is presented.

    The performance of a radar is affected by the operating conditions as well as radar systems(radar specifications). Atmospheric refraction and terrain are typical conditions of operation. The operating conditions depend on radar location. In particular, the detection performance of a radar is greatly affected by altitude. If the radar altitude gets higher, the radar can have good environment of radio wave at far range. Radar performance can also improve when the beam steering angle is properly adjusted. In this paper, we conducted research on the relationship between radar altitude and the beam steering angle, and variations in the detection performance of the radar. By using modeling and simulation methods, we developed a model by considering the external environment and radar systems to analyze the detection performance of the radar.

    Air-space based bistatic radar is a new radar concept of space-based radar, has strong anti-jamming ability and can economize satellite payloads. However, given the fact that the transmitter and receiver of the radar system are placed on airplane platform and satellite platform respectively, the Doppler frequency is determined by two platforms, which makes the clutter characteristic more complicated. This paper considers the actual beam exposure range, establishes the clutter model of air-space based bistatic radar and analyzes the performance of space-time adaptive processing (STAP) in different configurations. Experiment results show that system performance is greatly influenced by configuration and that air-space based bistatic radar is feasible in certain configurations. This can provide references for the study of air-space based bistatic radar.

    PDAF is a method of updating targets state estimation by using posteriori probability that measurements are originated from existing target in multi-target tracking. In this paper, we propose a multi-target tracking algorithm for falling cluster bombs separated from a mother bomb based on JPDAS method which is obtained by applying fixed-interval smoothing technique to JPDAF. The performance of JPDAF and JPDAS multi-target tracking algorithm is compared by observing the average of the difference between targets' state estimations obtained from 100 independent executions of two algorithms and targets' true states. Based on this, results of simulations for a radar tracking problem that show proposed JPDAS has better tracking performance than JPDAF is presented.

    This paper presents one of the first complete bistatic radar experiments by using a hitchhiking technique. The experiment involves the design of a low cost radar receiver that performs a bistatic radar pair with Barcelona's airport primary surveillance radar. This radar works as the transmitter subsystem, whereas the receiver subsystem is located at Barcelona's Telecommunication Engineers School, giving a baseline (distance between both subsystems) of 11 Km (Figure 1). The design and characterization of the RF front end, the synchronization system that allows to recover the staggered sequence pulse repetition frequency, and the radar measurements obtained with this bistatic system form also part of this work. The obtained results show that this kind of system is capable of increasing the robustness and performance of monostatic primary surveillance radars with a low additional cost.

    Target tracking has become more complicated as radar operating environments have become increasingly congested with clutter, interference, and countermeasures for jamming of radio frequency (RF) signals. As a result, the accuracy and performance of target tracking radars are further degraded. Three configurations of radar systems, namely, monostatic radar, bistatic radar, and passive radar, are commonly used today. The most conventional one is the monostatic radar defined by a co-located transmitter and receiver. In the bistatic radar system, the radar transmitter and receiver are physically separated by a large distance. A passive radar system is a derivative of the bistatic radar system, wherein radar functions are performed without the use of one's own transmitter. Instead, existing signals-of-opportunity (SOP) within the RF environment are opportunistically exploited to perform the radar functions. This paper presents a concept based on metacognition which entails dynamically switching the mode of operation between the three radar configurations to optimize target tracking accuracy. The paper provides an overview of the three radar configurations followed by the description of an approach for switching radar configuration among the three radars. Modeling and simulation of a passive radar system for target tracking in MATLAB is presented and followed by analysis and discussion of its performance.

    In this paper, we described the model of noise, target for tracking radar and range tracking, angle tracking, and Doppler frequency tracking for target acquisition and tracking. Target signal as well as the noise signal is modeled as random process varying with elapsed time. This paper addresses three areas of radar target tracking: range tracking, angle tracking, and Doppler frequency tracking. In general, range tracking is prerequisite to and inherent in both angle and Doppler frequency tracking systems. First, we introduced the several range tracking and described techniques for achieving range tracking. Second, we described the radar angle tracking techniques including conical scan, sequential lobing, and monopulse. Finally, we presented concepts and techniques for Doppler frequency tracking for several radar types.
