Working Through the Problems in Principles of Modern Radar
The basic solutions manual for Principles of Modern Radar covers the problem sets from the textbook by Richards, Schnur, and Griffiths. It walks through calculations for radar range equations, signal processing, detection theory, MTI and MTD filters, and related topics. The book itself is dense. The solutions manual is useful if you are working through it for a course or trying to build an actual understanding of radar engineering. I ran into a specific issue when I was using this material to prep for an exam on pulse-Doppler radar. Problem 4.7 in the main text asks about processing gain with a linear FM chirp, and the solution manual works through the time-bandwidth product in a way that assumes ideal conditions. The book does not fully address what happens when you have a non-ideal window function applied during pulse compression. The gain drops. Not dramatically, but enough to matter in practice. My workaround was to recalculate the matched filter output with a Hamming window applied to the chirp, which reduces the peak sidelobe ratio but also lowers the effective processing gain by about 1.5 dB. That detail never shows up in the basic manual. If you are designing something real, you need to know that the textbook solutions assume perfect processing.
Here is another thing the manual does not make clear. The radar range equation derivations treat the system noise figure as a fixed number. In an actual deployed radar, temperature variations and component aging shift the noise figure by a few decibels over time. That shifts your detection range more than most students expect. A 2 dB increase in system noise figure can drop your maximum range by roughly 10 to 12 percent. The manual covers the equation. It does not cover the drift.
What the Solutions Manual Covers
The manual works through problems from each chapter of the main text. You get step by step solutions for: The solutions are generally clear but sometimes skip intermediate steps. If you are new to this, you will find yourself filling in gaps. That is normal. The target detection chapter, specifically the treatment of Swerling cases, compresses a lot of material into a few lines. I had to go back to Skolnik's older text to get a fuller picture of what happens with a Swerling Case 2 target under slow scan conditions. Try the problem on your own first. The manual is too easy to fall back on prematurely. Write out the equations before looking at the solution. A lot of people skip this and just compare their final answer. That tells you nothing about where your reasoning went wrong.
Get the Full Details
Pay attention to the units. The textbook uses a mix of SI and conventional radar units. I have seen people get completely wrong answers because they did not convert dBm to watts or normalize the bandwidth correctly. This happens more often than you would think. For the signal processing chapters, actually code the simulations. Running a quick MATLAB or Python script for the pulse compression example takes about 15 minutes and gives you more understanding than reading the solution three times. The manual gives you the analytical answer. Coding it shows you the actual behavior.
Limitations and Gaps
The basic solutions manual has real shortcomings. It does not cover modern developments like MIMO radar configurations, statistical adaptive processing, or the computational methods used in current phased array systems. Those topics appear in later volumes or supplementary texts. If your course touches on those areas, the manual will not help you much. Another issue is that some of the numerical examples use simplified assumptions about clutter models. Real ground clutter follows a power law with elevation angle, and the manual treatments often assume simple Gaussian or uniform distributions. Your results will look clean in the exercises but may not hold up against real data. If you need more practical depth, supplement this with the IEEE Radar Conference proceedings or NASA technical reports on radar system design. The academic solutions are fine for learning the fundamentals. They are not substitutes for engineering judgment.
The manual is available through the publisher Scitech Publications and through major academic distributors. Prices vary, and the older editions are often sufficient unless your course references the latest version specifically. The core radar equations do not change between editions.
