where [[theta].sub.s] is the squint angle of the monopulse
beam, [[theta].sub.el] and [[theta].sub.az] are the differences of elevation angles and azimuth angles between the tracking axis and target, respectively, and [[theta].sub.A] is the angle difference between the beam maximum of quadrant 1 and target.

radar applications," IEEE Trans.
However, relatively little information has been published on monopulse
radar sea clutter, particularly on high-resolution coherent monopulse
radar sea clutter.
In the monopulse
radar system, the angular information of a target is extracted from the monopulse
ratio (MR), which is the ratio of the difference channel and the sum channel phasors.

antenna array of C-band," IEEE Antennas and Wireless Propagation Letters, vol.
In , a technique for obtaining simultaneously wide-angular nulling in the sum and difference patterns of a monopulse
antenna that utilizes two additional elements, one at each end of the original array, was investigated.
Our approach is of course motivated by the recently reported success of evolutionary multi-objective optimization techniques to the design of linear arrays [19, 20], time-modulated antenna arrays , and monopulse
circularly polarized siw slot array antenna in millimetre band," Journal of Electromagnetic Waves and Applications, Vol.
Recently, some studies show that 4D arrays have promising potentials for some practical applications, such as harmonic beamforming without phase shifting [12,13], direction finding [14,15], monopulse
radar design [16,17], adaptive nulling [18,19], and directional modulation for secure communication .
Raytheon Systems Limited and ROMATSA in February 2011 signed a contract for gradual acquisition, installation and commissioning of three radar systems MSSR Mode S (Monopulse
Secondary Surveillance Radar).
The second updated edition of Monopulse
Principles and Techniques comes from experts who offer technical details on the monopulse
radar, which sends additional information within a radar signal to avoid problems in signal strength.
The system has been selected for the location and identification of flights in the vicinity of Edinburgh Airport and replaced the existing Monopulse
Secondary Surveillance Radar (MSSR).
