Performance Evaluation of MIMO Cooperative Radar by Considering High Altitude Aeronautical Platforms
نویسنده
چکیده
In this paper, an analysis of radar range and probability of detection by the use of multiple-input multiple-output (MIMO) radar with cooperative high altitude aeronautical platforms (HAAP) relay (which could operate at stratospheric altitudes) is presented. In this study, a method of cooperative diversity known as ampliy-and-forward (AF) is considered and a target fluctuation model (Swerling I, II, III &IV) which aspires to generate probability of detection (Pd) and probability of false alarm (Pfa) using HAAP relay proposed. Cooperative transmission with MIMO radar allowed extra degrees of freedom, diversity gain to enhance the radar detection, search, identification and tracking of objects in space or the atmosphere in a clutter/ electronic countermeasures environment. Matlab simulations show that the proposed scheme provides an excellent BER performance and lower required signal-to-noise ratio (SNR) compared with the conventional radar systems. Keywords—Cooperative, HAAP, MIMO, Radar, Swerling.

The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...

In this paper, the problem of target detection in phased-MIMO radars is considered and target detection performance of phased-MIMO radars is compared with MIMO and phased-array radars. Phased-MIMO radars combine advantages of the MIMO and phased-array radars. In these radars, the transmit array will be partitioned into a number of subarrays that are allowed to overlap and each subarray transmit...
