3. Radar Pulse Modeling Problem. For this problem, you will draw PRIs following the template below. You must illustrate each PRI as shown and fill in the parameters shown in green. The drawing should be done by hand not in Matlab. For full credit, you must show the mathematics used to obtain the drawn values. If more than one target is present in the same PRI, you are required to include the multiple targets in the same sketch and indicate the A, t₁ and t₂ values for each of the target reflections. Ensure sufficient precision is used when labeling your parameters.
Amplitude (units) A trast? tslow "1 All J ţ, t₂ bearing = fast time. (units) tz a. Assume a radar system with the following parameters and operator settings Pt = 12 kW Gt = 28 dB Fc = 2 GHz Pulse Width = 6 us PRF = 1000 Hz Scan Rate = 10 RPM Beamwidth = 1.5 deg Transmitted waveform x = At sin (2TFct) when 0 <t<T where the voltage At = sqrt(2*P+*50 ohms) Two targets, each with an RCS of 5 dBsm, are known to be in the radar operating area. The first target is at 45 deg (North East) at a range separation of 6 nmi. The second target is at 48 deg at a range separation of 8 nmi. If tslow = 0 when bearing = 0 deg (true North), sketch the received signal time-series of the first and second PRI in the second scan that includes signal reflections of each target (i.e., first and second PRI containing target 1 and first and second PRI containing target 2 for a total of 4 plots). Ignore noise. Assume the beampattern is flat across the beamwidth and that F² = 1. Account for any power loss experienced by the signal due to range spreading. Rotate your antenna in a clockwise fashion. b. Repeat Problem 3a. However, assume the beamwidth is 5 deg. c. Repeat Problem 3a. However, instead of a steady PRF of 1000 Hz (i.e, a constant PRI of 1 ms), assume a staggered but repeating pattern of 3 PRIs of 1.04 ms, 0.9 ms, and 1.06 ms. That means, in slow time, the first PRI starts at 0 ms, the second at 1.04 ms, the third at 1.04+0.9 ms, the fourth at 1.04+0.9+1.06 ms, the fifth at 1.04+0.9+1.06+1.04 ms, the sixth at 1.04+0.9+1.06+1.04+0.9 ms and so on.
