In the frequency modulated continuous wave radar systems, when the transmitter uses periodic linear symmetric triangular wave modulation, the received signal after processed by the mixer will have many harmonics. In the single target detection, this effect can be ignored. However, in the multi-target detection, targets with different ranges and velocities lead to overlapping of the harmonics. Using...
The concept of multiple-input multiple-output (MIMO) radar is recently proposed inspired by recent advances in MIMO communications. A recently proposed statistical MIMO radar configuration is considered here, in which the transmit array antennas are widely spaced to enable spatial diversity with respect to the targets, while the receiver is an uniform linear array with the elements spaced half a wavelength...
Passive radar systems using emitters of opportunity for target detection and tracking have received significant interest recently, especially those which exploit frequency modulated (FM) radio stations and TV transmitters as signal sources. This paper is concerned with passive radar systems that utilize signal sources in the high frequency (HF) band (3-30 MHz), where due to long-distance ionospheric...
Modern phased array radar has changed national defense and the battlefield. The agility of the antenna beam of phased array radar is the key characteristic that has facilitated this change, coupled with the growth in processing, communication and presentation of data for decision making. This paper describes the modern battlefield and airborne phased array radar that are manufactured by Northrop Grumman...
Knowledge about the lateral target length may be useful in several applications such as convoy tracking and alerting a high resolution imaging mode for classification. We focus on the estimation of the apparent length of an extended target with particular emphasis on convoys of ground vehicles. The estimation is done by applying generalised power estimators to the output signals of an array antenna...
