Moving target detection radar system
For purposes like forward area surveillance, light, easily-carried radar systems are required. The most suitable technology which can be used here is a pulse-radar system in which provision is made for detecting the amplitude modulation of pulses due to target movement. It should be made to withstand severe physical conditions, rapid location of targets at any selected range must be made possible, and the operator must be able to identify targets by reference to the character of the modulation.
The Moving target detection radar system includes means for transmitting pulse signals and for receiving signals reflected from targets, multiple instances of range gates each for gating a received signal corresponding to a different range, modulation detecting means each controlled from a different range gate for detecting the modulation of signals received from a moving target and displaying the detected signal as modulations of a light source and also a viewing means including a rotatable prism for viewing the light sources. With this the linearly displaced images which are visible on a screen showing a moving target and the number of modulations of the source along the displacement line indicates the frequency and hence the rate of radial movement of the target.
A typical system specification for this purpose can be :
Operating Frequency X band (3 cm) Solid Beamwidth 5 degrees between 3 dB points Peak Transmitter Power 11/2 Kw Pulse Length 0.25 u secs Pulse Repetition Frequency 4,000 pulses/sec. Super-heterodyne Receiver
